At Made by Google 2025, we announced that the new Google Pixel 10 phones will support C2PA Content Credentials in Pixel Camera and Google Photos. This announcement represents a series of steps towards greater digital media transparency:
These capabilities are powered by Google Tensor G5, Titan M2 security chip, the advanced hardware-backed security features of the Android platform, and Pixel engineering expertise.
In this post, we’ll break down our architectural blueprint for bringing a new level of trust to digital media, and how developers can apply this model to their own apps on Android.
Generative AI can help us all to be more creative, productive, and innovative. But it can be hard to tell the difference between content that’s been AI-generated, and content created without AI. The ability to verify the source and history—or provenance—of digital content is more important than ever.
Content Credentials convey a rich set of information about how media such as images, videos, or audio files were made, protected by the same digital signature technology that has secured online transactions and mobile apps for decades. It empowers users to identify AI-generated (or altered) content, helping to foster transparency and trust in generative AI. It can be complemented by watermarking technologies such as SynthID.
Content Credentials are an industry standard backed by a broad coalition of leading companies for securely conveying the origin and history of media files. The standard is developed by the Coalition for Content Provenance and Authenticity (C2PA), of which Google is a steering committee member.
The traditional approach to classifying digital image content has focused on categorizing content as “AI” vs. “not AI”. This has been the basis for many legislative efforts, which have required the labeling of synthetic media. This traditional approach has drawbacks, as described in Chapter 5 of this seminal report by Google. Research shows that if only synthetic content is labeled as “AI”, then users falsely believe unlabeled content is “not AI”, a phenomenon called “the implied truth effect”. This is why Google is taking a different approach to applying C2PA Content Credentials.
Instead of categorizing digital content into a simplistic “AI” vs. “not AI”, Pixel 10 takes the first steps toward implementing our vision of categorizing digital content as either i) media that comes with verifiable proof of how it was made or ii) media that doesn't.
Given the broad range of scenarios in which Content Credentials are attached by these apps, we designed our C2PA implementation architecture from the onset to be:
Good actors in the C2PA ecosystem are motivated to ensure that provenance data is trustworthy. C2PA Certification Authorities (CAs), such as Google, are incentivized to only issue certificates to genuine instances of apps from trusted developers in order to prevent bad actors from undermining the system. Similarly, app developers want to protect their C2PA claim signing keys from unauthorized use. And of course, users want assurance that the media files they rely on come from where they claim. For these reasons, the C2PA defined the Conformance Program.
The Pixel Camera application on the Pixel 10 lineup has achieved Assurance Level 2, the highest security rating currently defined by the C2PA Conformance Program. This was made possible by a strong set of hardware-backed technologies, including Tensor G5 and the certified Titan M2 security chip, along with Android’s hardware-backed security APIs. Only mobile apps running on devices that have the necessary silicon features and Android APIs can be designed to achieve this assurance level. We are working with C2PA to help define future assurance levels that will push protections even deeper into hardware.
Achieving Assurance Level 2 requires verifiable, difficult-to-forge evidence. Google has built an end-to-end system on Pixel 10 devices that verifies several key attributes. However, the security of any claim is fundamentally dependent on the integrity of the application and the OS, an integrity that relies on both being kept current with the latest security patches.
The C2PA Conformance Program requires verifiable artifacts backed by a hardware Root of Trust, which Android provides through features like Key Attestation. This means Android developers can leverage these same tools to build apps that meet this standard for their users.
The robust security stack we described is the foundation of privacy. But Google takes steps further to ensure your privacy even as you use Content Credentials, which required solving two additional challenges:
Challenge 1: Server-side Processing of Certificate Requests. Google’s C2PA Certification Authorities must certify new cryptographic keys generated on-device. To prevent fraud, these certificate enrollment requests need to be authenticated. A more common approach would require user accounts for authentication, but this would create a server-side record linking a user's identity to their C2PA certificates—a privacy trade-off we were unwilling to make.
Our Solution: Anonymous, Hardware-Backed Attestation. We solve this with Android Key Attestation, which allows Google CAs to verify what is being used (a genuine app on a secure device) without ever knowing who is using it (the user). Our CAs also enforce a strict no-logging policy for information like IP addresses that could tie a certificate back to a user.
Challenge 2: The Risk of Traceability Through Key Reuse. A significant privacy risk in any provenance system is traceability. If the same device or app-specific cryptographic key is used to sign multiple photos, those images can be linked by comparing the key. An adversary could potentially connect a photo someone posts publicly under their real name with a photo they post anonymously, deanonymizing the creator.
Our Solution: Unique Certificates. We eliminate this threat with a maximally private approach. Each key and certificate is used to sign exactly one image. No two images ever share the same public key, a "One-and-Done" Certificate Management Strategy, making it cryptographically impossible to link them. This engineering investment in user privacy is designed to set a clear standard for the industry.
Overall, you can use Content Credentials on Pixel 10 without fear that another person or Google could use it to link any of your images to you or one another.
Implementations of Content Credentials use trusted time-stamps to ensure the credentials can be validated even after the certificate used to produce them expires. Obtaining these trusted time-stamps typically requires connectivity to a Time-Stamping Authority (TSA) server. But what happens if the device is offline?
This is not a far-fetched scenario. Imagine you’ve captured a stunning photo of a remote waterfall. The image has Content Credentials that prove that it was captured by a camera, but the cryptographic certificate used to produce them will eventually expire. Without a time-stamp, that proof could become untrusted, and you're too far from a cell signal, which is required to receive one.
To solve this, Pixel developed an on-device, offline TSA.
Powered by the security features of Tensor, Pixel maintains a trusted clock in a secure environment, completely isolated from the user-controlled one in Android. The clock is synchronized regularly from a trusted source while the device is online, and is maintained even after the device goes offline (as long as the phone remains powered on). This allows your device to generate its own cryptographically-signed time-stamps the moment you press the shutter—no connection required. It ensures the story behind your photo remains verifiable and trusted after its certificate expires, whether you took it in your living room or at the top of a mountain.
C2PA Content Credentials are not the sole solution for identifying the provenance of digital media. They are, however, a tangible step toward more media transparency and trust as we continue to unlock more human creativity with AI.
In our initial implementation of Content Credentials on the Android platform and Pixel 10 lineup, we prioritized a higher standard of privacy, security, and usability. We invite other implementers of Content Credentials to evaluate our approach and leverage these same foundational hardware and software security primitives. The full potential of these technologies can only be realized through widespread ecosystem adoption.
We look forward to adding Content Credentials across more Google products in the near future.
Google has been at the forefront of protecting users from the ever-growing threat of scams and fraud with cutting-edge technologies and security expertise for years. In 2024, scammers used increasingly sophisticated tactics and generative AI-powered tools to steal more than $1 trillion from mobile consumers globally, according to the Global Anti-Scam Alliance. And with the majority of scams now delivered through phone calls and text messages, we’ve been focused on making Android’s safeguards even more intelligent with powerful Google AI to help keep your financial information and data safe.
Today, we’re launching two new industry-leading AI-powered scam detection features for calls and text messages, designed to protect users from increasingly complex and damaging scams. These features specifically target conversational scams, which can often appear initially harmless before evolving into harmful situations. To enhance our detection capabilities, we partnered with financial institutions around the world to better understand the latest advanced and most common scams their customers are facing. For example, users are experiencing more conversational text scams that begin innocently, but gradually manipulate victims into sharing sensitive data, handing over funds, or switching to other messaging apps. And more phone calling scammers are using spoofing techniques to hide their real numbers and pretend to be trusted companies.
Traditional spam protections are focused on protecting users before the conversation starts, and are less effective against these latest tactics from scammers that turn dangerous mid-conversation and use social engineering techniques. To better protect users, we invested in new, intelligent AI models capable of detecting suspicious patterns and delivering real-time warnings over the course of a conversation, all while prioritizing user privacy.
We’re building on our enhancements to existing Spam Protection in Google Messages that strengthen defenses against job and delivery scams, which are continuing to roll out to users. We’re now introducing Scam Detection to detect a wider range of fraudulent activities. Scam Detection in Google Messages uses powerful Google AI to proactively address conversational scams by providing real-time detection even after initial messages are received. When the on-device AI detects a suspicious pattern in SMS, MMS, and RCS messages, users will now get a message warning of a likely scam with an option to dismiss or report and block the sender.
As part of the Spam Protection setting, Scam Detection on Google Messages is on by default and only applies to conversations with non-contacts. Your privacy is protected with Scam Detection in Google Messages, with all message processing remaining on-device. Your conversations remain private to you; if you choose to report a conversation to help reduce widespread spam, only sender details and recent messages with that sender are shared with Google and carriers. You can turn off Spam Protection, which includes Scam Detection, in your Google Messages at any time.
Scam Detection in Google Messages is launching in English first in the U.S., U.K. and Canada and will expand to more countries soon.
More than half of Americans reported receiving at least one scam call per day in 2024. To combat the rise of sophisticated conversational scams that deceive victims over the course of a phone call, we introduced Scam Detection late last year to U.S.-based English-speaking Phone by Google public beta users on Pixel phones.
We use AI models processed on-device to analyze conversations in real-time and warn users of potential scams. If a caller, for example, tries to get you to provide payment via gift cards to complete a delivery, Scam Detection will alert you through audio and haptic notifications and display a warning on your phone that the call may be a scam.
During our limited beta, we analyzed calls with Gemini Nano, Google’s built-in, on-device foundation model, on Pixel 9 devices and used smaller, robust on-device machine-learning models for Pixel 6+ users. Our testing showed that Gemini Nano outperformed other models, so as a result, we're currently expanding the availability of the beta to bring the most capable Scam Detection to all English-speaking Pixel 9+ users in the U.S.
Similar to Scam Detection in messaging, we built this feature to protect your privacy by processing everything on-device. Call audio is processed ephemerally and no conversation audio or transcription is recorded, stored on the device, or sent to Google or third parties. Scam Detection in Phone by Google is off by default to give users control over this feature, as phone call audio is more ephemeral compared to messages, which are stored on devices. Scam Detection only applies to calls that could potentially be scams, and is never used during calls with your contacts. If enabled, Scam Detection will beep at the start and during the call to notify participants the feature is on. You can turn off Scam Detection at any time, during an individual call or for all future calls.
According to our research and a Scam Detection beta user survey, these types of alerts have already helped people be more cautious on the phone, detect suspicious activity, and avoid falling victim to conversational scams.
With AI-powered innovations like Scam Detection in Messages and Phone by Google, we're giving you more tools to stay one step ahead of bad actors. We're constantly working with our partners across the Android ecosystem to help bring new security features to even more users. Together, we’re always working to keep you safe on Android.
Based on third-party research funded by Google LLC in Feb 2025 comparing the Pixel 9 Pro, iPhone 16 Pro, Samsung S24+ and Xiaomi 14 Ultra. Evaluation based on no-cost smartphone features enabled by default. Some features may not be available in all countries. ↩
User safety is at the heart of everything we do at Google. Our mission to make technology helpful for everyone means building features that protect you while keeping your privacy top of mind. From Gmail’s defenses that stop more than 99.9% of spam, phishing and malware, to Google Messages’ advanced security that protects users from 2 billion suspicious messages a month and beyond, we're constantly developing and expanding protection features that help keep you safe.
We're introducing two new real-time protection features that enhance your safety, all while safeguarding your privacy: Scam Detection in Phone by Google to protect you from scams and fraud, and Google Play Protect live threat detection with real-time alerts to protect you from malware and dangerous apps.
These new security features are available first on Pixel, and are coming soon to more Android devices.
Scammers steal over $1 trillion dollars a year from people, and phone calls are their favorite way to do it. Even more alarming, scam calls are evolving, becoming increasingly more sophisticated, damaging and harder to identify. That’s why we’re using the best of Google AI to identify and stop scams before they can do harm with Scam Detection.
Real-time protection, built with your privacy in mind.
We’re now rolling out Scam Detection to English-speaking Phone by Google public beta users in the U.S. with a Pixel 6 or newer device.
To provide feedback on your experience, please click on Phone by Google App -> Menu -> Help & Feedback -> Send Feedback. We look forward to learning from this beta and your feedback, and we’ll share more about Scam Detection in the months ahead.
Google Play Protect works non-stop to protect you in real-time from malware and unsafe apps. Play Protect analyzes behavioral signals related to the use of sensitive permissions and interactions with other apps and services.With live threat detection, if a harmful app is found, you'll now receive a real-time alert, allowing you to take immediate action to protect your device. By looking at actual activity patterns of apps, live threat detection can now find malicious apps that try extra hard to hide their behavior or lie dormant for a time before engaging in suspicious activity.
At launch, live threat detection will focus on stalkerware, code that may collect personal or sensitive data for monitoring purposes without user consent, and we will explore expanding its detection to other types of harmful apps in the future. All of this protection happens on your device in a privacy preserving way through Private Compute Core, which allows us to protect users without collecting data.
Live threat detection with real-time alerts in Google Play Protect are now available on Pixel 6+ devices and will be coming to additional phone makers in the coming months.
Pixel phones have earned a well-deserved reputation for being security-conscious. In this blog, we'll take a peek under the hood to see how Pixel mitigates common exploits on cellular basebands.
Smartphones have become an integral part of our lives, but few of us think about the complex software that powers them, especially the cellular baseband – the processor on the device responsible for handling all cellular communication (such as LTE, 4G, and 5G). Most smartphones use cellular baseband processors with tight performance constraints, making security hardening difficult. Security researchers have increasingly exploited this attack vector and routinely demonstrated the possibility of exploiting basebands used in popular smartphones.
The good news is that Pixel has been deploying security hardening mitigations in our basebands for years, and Pixel 9 represents the most hardened baseband we've shipped yet. Below, we’ll dive into why this is so important, how specifically we’ve improved security, and what this means for our users.
The Cellular Baseband
The cellular baseband within a smartphone is responsible for managing the device's connectivity to cellular networks. This function inherently involves processing external inputs, which may originate from untrusted sources. For instance, malicious actors can employ false base stations to inject fabricated or manipulated network packets. In certain protocols like IMS (IP Multimedia Subsystem), this can be executed remotely from any global location using an IMS client.
The firmware within the cellular baseband, similar to any software, is susceptible to bugs and errors. In the context of the baseband, these software vulnerabilities pose a significant concern due to the heightened exposure of this component within the device's attack surface. There is ample evidence demonstrating the exploitation of software bugs in modem basebands to achieve remote code execution, highlighting the critical risk associated with such vulnerabilities.
The State of Baseband Security
Baseband security has emerged as a prominent area of research, with demonstrations of software bug exploitation featuring in numerous security conferences. Many of these conferences now also incorporate training sessions dedicated to baseband firmware emulation, analysis, and exploitation techniques.
Recent reports by security researchers have noted that most basebands lack exploit mitigations commonly deployed elsewhere and considered best practices in software development. Mature software hardening techniques that are commonplace in the Android operating system, for example, are often absent from cellular firmwares of many popular smartphones.
There are clear indications that exploit vendors and cyber-espionage firms abuse these vulnerabilities to breach the privacy of individuals without their consent. For example, 0-day exploits in the cellular baseband are being used to deploy the Predator malware in smartphones. Additionally, exploit marketplaces explicitly list baseband exploits, often with relatively low payouts, suggesting a potential abundance of such vulnerabilities. These vulnerabilities allow attackers to gain unauthorized access to a device, execute arbitrary code, escalate privileges, or extract sensitive information.
Recognizing these industry trends, Android and Pixel have proactively updated their Vulnerability Rewards Program in recent years, placing a greater emphasis on identifying and addressing exploitable bugs in connectivity firmware.
Building a Fortress: Proactive Defenses in the Pixel Modem
In response to the rising threat of baseband security attacks, Pixel has incrementally incorporated many of the following proactive defenses over the years, with the Pixel 9 phones (Pixel 9, Pixel 9 Pro, Pixel 9 Pro XL and Pixel 9 Pro Fold) showcasing the latest features:
We also leverage a number of bug detection tools, such as address sanitizer, during our testing process. This helps us identify software bugs and patch them prior to shipping devices to our users.
The Pixel Advantage: Combining Protections for Maximum Security
Security hardening is difficult and our work is never done, but when these security measures are combined, they significantly increase Pixel 9’s resilience to baseband attacks.
Pixel's proactive approach to security demonstrates a commitment to protecting its users across the entire software stack. Hardening the cellular baseband against remote attacks is just one example of how Pixel is constantly working to stay ahead of the curve when it comes to security.
Special thanks to our colleagues who supported our cellular baseband hardening efforts: Dominik Maier, Shawn Yang, Sami Tolvanen, Pirama Arumuga Nainar, Stephen Hines, Kevin Deus, Xuan Xing, Eugene Rodionov, Stephan Somogyi, Wes Johnson, Suraj Harjani, Morgan Shen, Valery Wu, Clint Chen, Cheng-Yi He, Estefany Torres, Hungyen Weng, Jerry Hung, Sherif Hanna
You, me, and the entire ecosystem! GPUs (graphics processing units) are critical in delivering rich visual experiences on mobile devices. However, the GPU software and firmware stack has become a way for attackers to gain permissions and entitlements (privilege escalation) to Android-based devices. There are plenty of issues in this category that can affect all major GPU brands, for example, CVE-2023-4295, CVE-2023-21106, CVE-2021-0884, and more. Most exploitable GPU vulnerabilities are in the implementation of the GPU kernel mode modules. These modules are pieces of code that load/unload during runtime, extending functionality without the need to reboot the device.
Proactive testing is good hygiene as it can lead to the detection and resolution of new vulnerabilities before they’re exploited. It’s also one of the most complex investigations to do as you don’t necessarily know where the vulnerability will appear (that’s the point!). By combining the expertise of Google’s engineers with IP owners and OEMs, we can ensure the Android ecosystem retains a strong measure of integrity.
When researching vulnerabilities, GPUs are a popular target due to:
Nobody wants a slow, unresponsive device; any hits to GPU performance could result in a noticeably degraded user experience. As such, the GPU software stack in Android relies on an in-process HAL model where the API & user space drivers communicating with the GPU kernel mode module are running directly within the context of apps, thus avoiding IPC (interprocess communication). This opens the door for potentially untrusted code from a third party app being able to directly access the interface exposed by the GPU kernel module. If there are any vulnerabilities in the module, the third party app has an avenue to exploit them. As a result, a potentially untrusted code running in the context of the third party application is able to directly access the interface exposed by the GPU kernel module and exploit potential vulnerabilities in the kernel module.
Additionally, the implementation of GPU subsystems (and kernel modules specifically) from major OEMs are increasingly complex. Kernel modules for most GPUs are typically written in memory unsafe languages such as C, which are susceptible to memory corruption vulnerabilities like buffer overflow.
Great news, we already have! Who’s we? The Android Red Team and Arm! We’ve worked together to run an engagement on the Mali GPU (more on that below), but first, a brief introduction:
Android Red Team
The Android Red Team performs time-bound security assessment engagements on all aspects of the Android open source codebase and conducts regular security reviews and assessments of internal Android components. Throughout these engagements, the Android Red Team regularly collaborates with 3rd party software and hardware providers to analyze and understand proprietary and “closed source” code repositories and relevant source code that are utilized by Android products with the sole objective to identify security risks and potential vulnerabilities before they can be exploited by adversaries outside of Android. This year, the Android Red Team collaborated directly with our industry partner, Arm, to conduct the Mali GPU engagement and further secure millions of Android devices.
Arm Product Security and GPU Teams
Arm has a central product security team that sets the policy and practice across the company. They also have dedicated product security experts embedded in engineering teams. Arm operates a systematic approach which is designed to prevent, discover, and eliminate security vulnerabilities. This includes a Security Development Lifecycle (SDL), a Monitoring capability, and Incident Response. For this collaboration the Android Red Teams were supported by the embedded security experts based in Arm’s GPU engineering team.
Google’s Android Security teams and Arm have been working together for a long time. Security requirements are never static, and challenges exist with all GPU vendors. By frequently sharing expertise, the Android Red Team and Arm were able to accelerate detection and resolution. Investigations of identified vulnerabilities, potential remediation strategies, and hardening measures drove detailed analyses and the implementation of fixes where relevant.
Recent research focused on the Mali GPU because it is the most popular GPU in today's Android devices. Collaborating on GPU security allowed us to:
Investigations have led to significant improvements, leveling up the security of the GPU software/firmware stack across a wide segment of the Android ecosystem.
One key component of the GPU subsystem is its kernel mode driver. During this engagement, both the Android Red Team and Arm invested significant effort looking at the Mali kbase kernel driver. Due to its complexity, fuzzing was chosen as the primary testing approach for this area. Fuzzing automates and scales vulnerability discovery in a way not possible via manual methods. With help from Arm, the Android Red Team added more syzkaller fuzzing descriptions to match the latest Mali kbase driver implementation.
The team built a few customizations to enable fuzzing the Mali kbase driver in the cloud, without physical hardware. This provided a huge improvement to fuzzing performance and scalability. With the Pixel team’s support, we also were able to set up fuzzing on actual Pixel devices. Through the combination of cloud-based fuzzing, Pixel-based fuzzing, and manual review, we were able to uncover two memory issues in Pixel’s customization of driver code (CVE-2023-48409 and CVE-2023-48421).
Both issues occurred inside of the gpu_pixel_handle_buffer_liveness_update_ioctl function, which is implemented by the Pixel team as part of device specific customization. These are both memory issues caused by integer overflow problems. If exploited carefully alongside other vulnerabilities, these issues could lead to kernel privilege escalation from user space. Both issues were fixed and the patch was released to affected devices in Pixel security bulletin 2023-12-01.
Firmware is another fundamental building block of the GPU subsystem. It’s the intermediary working with kernel drivers and GPU hardware. In many cases, firmware functionality is directly/indirectly accessible from the application. So “application ⇒ kernel ⇒ firmware ⇒ kernel” is a known attack flow in this area. Also, in general, firmware runs on embedded microcontrollers with limited resources. Commonly used security kernel mitigations (ASLR, stack protection, heap protection, certain sanitizers, etc.) might not be applicable to firmware due to resource constraints and performance impact. This can make compromising firmware easier, in some cases, than directly compromising kernel drivers from user space. To test the integrity of existing firmware, the Android Red Team and Arm worked together to perform both fuzzing and formal verification along with manual analysis. This multi-pronged approach led to the discovery of CVE-2024-0153, which had a patch released in the July 2024 Android Security Bulletin.
CVE-2024-0153 happens when GPU firmware handles certain instructions. When handling such instructions, the firmware copies register content into a buffer. There are size checks before the copy operation. However, under very specific conditions, an out-of-bounds write happens to the destination buffer, leading to a buffer overflow. When carefully manipulated, this overflow will overwrite some other important structures following the buffer, causing code execution inside of the GPU firmware.
The conditions necessary to reach and potentially exploit this issue are very complex as it requires a deep understanding of how instructions are executed. With collective expertise, the Android Red Team and Arm were able to verify the exploitation path and leverage the issue to gain limited control of GPU firmware. This eventually circled back to the kernel to obtain privilege escalation. Arm did an excellent job to respond quickly and remediate the issue. Altogether, this highlights the strength of collaboration between both teams to dive deeper.
It’s known that attackers exploit GPU vulnerabilities in the wild, and time to patch is crucial to reduce risk of exploitation and protect users. As a result of this engagement, nine new Security Test suite (STS) tests were built to help partners automatically check their builds for missing Mali kbase patches. (Security Test Suite is software provided by Google to help partners automate the process of checking their builds for missing security patches.)
The Arm Product Security Team is actively involved in security-focused industry communities and collaborates closely with its ecosystem partners. The engagement with the Android Red Team, for instance, provides valuable enablement that drives best practices and product excellence. Building on this collaborative approach, Arm is complementing its product security assurance capabilities with a bug bounty program. This investment will expand Arm’s efforts to identify potential vulnerabilities. For more information on Arm's product security initiatives, please visit this product security page.
The Android Red Team and Arm continue to work together to proactively raise the bar on GPU security. With thorough testing, rapid fixing, and updates to the security test suite, we’re improving the ecosystem for Android users. The Android Red Team looks forward to replicating this working relationship with other ecosystem partners to make devices more secure.
Helping Pixel owners upgrade to the easier, safer way to sign in
Your phone contains a lot of your personal information, from financial data to photos. Pixel phones are designed to help protect you and your data, and make security and privacy as easy as possible. This is why the Pixel team has been especially excited about passkeys—the easier, safer alternative to passwords.
Passkeys are safer because they’re unique to each account, and are more resistant against online attacks such as phishing. They’re easier to use because there’s nothing for you to remember: when it’s time to sign in, using a passkey is as simple as unlocking your device with your face or fingerprint, or your PIN/pattern/password.
Google is working to accelerate passkey adoption. We’ve launched support for passkeys on Google platforms such as Android and Chrome, and recently we announced that we’re making passkeys a default option across personal Google Accounts. We’re also working with our partners across the industry to make passkeys available on more websites and apps.
Recently, we took things a step further. As part of last December’s Pixel Feature Drop, we introduced a new feature to Google Password Manager: passkey upgrades. With this new feature, Google Password Manager will let you discover which of your accounts support passkeys, and help you upgrade with just a few taps.
This new passkey upgrade experience is now available on Pixel phones (starting from Pixel 5a) as well as Pixel Tablet. Google Password manager will incorporate these updates for other platforms in the future.
Every day, billions of people around the world trust Google products to enrich their lives and provide helpful features – across mobile devices, smart home devices, health and fitness devices, and more. We keep more people safe online than anyone else in the world, with products that are secure by default, private by design and that put you in control. As our advancements in knowledge and computing grow to deliver more help across contexts, locations and languages, our unwavering commitment to protecting your information remains.
That’s why Pixel phones are designed from the ground up to help protect you and your sensitive data while keeping you in control. We’re taking our industry-leading approach to security and privacy to the next level with Google Pixel 7 and Pixel 7 Pro, our most secure and private phones yet, which were recently recognized as the highest rated for security when tested among other smartphones by a third-party global research firm.1
Pixel phones also get better every few months with Feature Drops that provide the latest product updates, tips and tricks from Google. And Pixel 7 and Pixel 7 Pro users will receive at least five years of security updates2, so your Pixel gets even more secure over time.
Your protection, built into Pixel
Your digital life and most sensitive information lives on your phone: financial information, passwords, personal data, photos – you name it. With Google Tensor G2 and our custom Titan M2 security chip, Pixel 7 and Pixel 7 Pro have multiple layers of hardware security to help keep you and your personal information safe. We take a comprehensive, end-to-end approach to security with verifiable protections at each layer - the network, application, operating system and multiple layers on the silicon itself. If you use Pixel for your business, this approach helps protect your company data, too.
Google Tensor G2 is Pixel’s newest powerful processor custom built with Google AI, and makes Pixel 7 faster, more efficient and secure3. Every aspect of Tensor G2 was designed to improve Pixel's performance and efficiency for great battery life, amazing photos and videos.
Tensor’s built-in security core works with our Titan M2 security chip to keep your personal information, PINs and passwords safe. Titan family chips are also used to protect Google Cloud data centers and Chromebooks, so the same hardware that protects Google servers also secures your sensitive information stored on Pixel.
And, in a first for Google, Titan M2 hardware has now been certified under Common Criteria PP0084: the international gold standard for hardware security components also used for identity, SIM cards, and bankcard security chips.4 This means that the Titan M2 hardware meets the same rigorous protection guidelines trusted by banks, carriers, and governments.
To achieve the certification we went through rigorous third party lab testing by SGS Brightsight, a leading international security lab, and received certification against CC PP0084 with AVA_VAN.5 for the Titan M2 hardware and cryptography library from the Netherlands scheme for Certification in the Area of IT Security (NSCIB). Of all those numbers and acronyms the part we’re most proud of is that Titan hardware passed the highest level of vulnerability assessment (AVA_VAN.5) - the truest measure of resilience to advanced, methodical attacks.
This process took us more than three years to complete. The certification not only requires chip hardware to resist invasive penetration testing, but also mandates audits of the chip design and manufacturing process itself. The benefit for consumers? The now certified Titan M2 chip makes your phone even more resilient to sophisticated attacks.5
Private by design
Evolving our security and privacy standards to our fast-paced world requires new approaches as well. Earlier this year at I/O, we introduced Protected Computing, a toolkit of technologies that transforms how, when, and where personal data is processed to protect your privacy and security. Our approach focuses on:
Many elements of Protected Computing can be found on the new Pixel 7:
On Android, Private Compute Core keeps your information and AI-driven personalizations private with on-device processing. Data from features like Now Playing, Live Caption and Smart Reply in Messages are all processed on device and are never sent to Google to maintain your privacy. And even your device backups to the cloud are end-to-end encrypted using Titan in the cloud.6
With Google Tensor G2, Pixel’s advanced privacy protection also now covers audio data from events like cough and snore detection on Pixel 7.7 Audio data from cough and snore detection is never stored by or sent to Google to maintain your privacy.
On Pixel 7, Tensor G2 helps safeguard your system with the Android Virtualization Framework, unlocking improved security protections like enabling system update integrity checking to occur on-the-fly, reducing boot time after an update.
Extra protection when you’re online
Helping to keep you safe when you use your phone to browse the web and use apps is also critical. This is where a Virtual Private Network (VPN) comes in. A VPN helps protect your online activity from anyone who might try to access it by encrypting your network traffic to turn it into an unreadable format, and masking your original IP address. Typically, if you want a VPN on your phone, you need to get one from a third party.
To ensure more people have access to enhanced security, later this year, Pixel 7 and Pixel 7 Pro owners will be able to use VPN by Google One, at no extra cost.8 VPN by Google One is verifiably private, and will allow you to tap into Google’s world-class security for peace of mind when you connect online. With VPN by Google One, Pixel helps protect your online activity at a network level. Think of it like an extra layer of protection for your online security.
VPN by Google One creates a high-performance secure connection to the web so your browsing and app data is sent and received via an encrypted pathway. A few simple taps will activate the VPN to help keep your network traffic private from internet providers and hackers, giving you peace of mind when using cellular data, home Wi-Fi, and especially when connected to public networks, like a café or airport Wi-Fi. No need to worry about online intruders, hackers, or unsecure networks.
Unlike traditional VPN services, VPN by Google One uses Protected Computing to technically make it impossible for anyone at a network level, even VPN by Google One, to link your online traffic with your account or identity. VPN by Google One will be available at no extra cost as long as your phone continues to receive security updates. See here to learn more about VPN by Google One.
More protection and privacy with Android 13
Pixel 7 and Pixel 7 Pro have built-in anti-phishing protections from Android that scan for potential threats from phone calls, text messages and emails, and more anti-phishing protections enabled out-of-the-box than smartphones from leading competitors.9 In fact, Messages alone protects consumers against 1.5 billion spam messages per month.
Android also resets permissions for apps you haven’t used for an extended time. In a typical month, Android automatically resets more than 3 billion permissions affecting more than 1 billion installed apps. Similarly, if you use clipboard on Android 13, your history is automatically deleted after a period of time. This blocks apps running in the foreground from seeing old information that you previously copied.
You’re in control
Core to your safety is knowing that you’re in control. You always have control over your settings and devices across all of our products. With Android 13, coming soon through a Feature Drop, Pixel 7 and Pixel 7 Pro will give you additional ways to stay in control of your privacy and what you share with first and third-party apps. With Quick Settings, you can act on security issues as they arise, or review which apps are running in the background and easily stop them. You’ll have a single destination for reviewing your security and privacy settings, risk levels and information, making it easier to manage your safety status.
With this new experience, you can review actionable steps to improve your safety status, like revoking a permission or app. This page will also have new action cards to notify you of any safety risks and provide timely recommendations on how to enhance your privacy. And with a single tap, you can grant or remove permissions to data that you don’t want to share with compatible apps. This will be coming soon first to Pixel devices later this year, and other Android phones soon after.
Verifiably secure
As computing extends to more devices and use cases, Google is committed to innovating in security and being transparent about the processes that we take to get there. We are leading the industry in verifiable security by not only having products that are tested against real-world threats (like advanced spam, phishing and malware attacks), but also in publishing the results of penetration tests, security audits, and industry certifications across our Pixel and Nest products.
Another way to verify our security is through our Android and Google Devices Security Reward Program where we reward security researchers who find vulnerabilities across products, including Pixel, Nest and Fitbit. Last year on Android, we awarded nearly $3 million dollars, creating a valuable feedback loop between us and the security research community and, most importantly, helping us keep our users safe.

With Pixel 6 and Pixel 6 Pro, we’re launching our most secure Pixel phone yet, with 5 years of security updates and the most layers of hardware security. These new Pixel smartphones take a layered security approach, with innovations spanning across the Google Tensor system on a chip (SoC) hardware to new Pixel-first features in the Android operating system, making it the first Pixel phone with Google security from the silicon all the way to the data center. Multiple dedicated security teams have also worked to ensure that Pixel’s security is provable through transparency and external validation.
Secure to the Core
Google has put user data protection and transparency at the forefront of hardware security with Google Tensor. Google Tensor’s main processors are Arm-based and utilize TrustZone™ technology. TrustZone is a key part of our security architecture for general secure processing, but the security improvements included in Google Tensor go beyond TrustZone.
The Google Tensor security core is a custom designed security subsystem dedicated to the preservation of user privacy. It's distinct from the application processor, not only logically, but physically, and consists of a dedicated CPU, ROM, one-time-programmable (OTP) memory, crypto engine, internal SRAM, and protected DRAM. For Pixel 6 and 6 Pro, the security core’s primary use cases include protecting user data keys at runtime, hardening secure boot, and interfacing with Titan M2TM.
Your secure hardware is only as good as your secure OS, and we are using Trusty, our open source trusted execution environment. Trusty OS is the secure OS used both in TrustZone and the Google Tensor security core.
With Pixel 6 and Pixel 6 Pro your security is enhanced by the new Titan M2TM, our discrete security chip, fully designed and developed by Google. In this next generation chip, we moved to an in-house designed RISC-V processor, with extra speed and memory, and made it even more resilient to advanced attacks. Titan M2TM has been tested against the most rigorous standard for vulnerability assessment, AVA_VAN.5, by an independent, accredited evaluation lab. Titan M2™ supports Android Strongbox, which securely generates and stores keys used to protect your PINs and password, and works hand-in-hand with Google Tensor security core to protect user data keys while in use in the SoC.
Moving a step higher in the system, Pixel 6 and Pixel 6 Pro ship with Android 12 and a slew of Pixel-first and Pixel-exclusive features.
Enhanced Controls
We aim to give users better ways to control their data and manage their devices with every release of Android. Starting with Android 12 on Pixel, you can use the new Security hub to manage all your security settings in one place. It helps protect your phone, apps, Google Account, and passwords by giving you a central view of your device’s current configuration. Security hub also provides recommendations to improve your security, helping you decide what settings best meet your needs.
For privacy, we are launching Privacy Dashboard, which will give you a simple and clear timeline view of the apps that have accessed your location, microphone and camera in the last 24 hours. If you notice apps that are accessing more data than you expected, the dashboard provides a path to controls to change those permissions on the fly.
To provide additional transparency, new indicators in Pixel’s status bar will show you when your camera and mic are being accessed by apps. If you want to disable that access, new privacy toggles give you the ability to turn off camera or microphone access across apps on your phone with a single tap, at any time.
The Pixel 6 and Pixel 6 Pro also include a toggle that lets you remove your device’s ability to connect to less-secure 2G networks. While necessary in certain situations, accessing 2G networks can open up additional attack vectors; this toggle helps users mitigate those risks when 2G connectivity isn’t needed.
Built-in security
By making all of our products secure by default, Google keeps more people safe online than anyone else in the world. With the Pixel 6 and Pixel 6 Pro, we’re also ratcheting up the dial on default, built-in protections.
Our new optical under-display fingerprint sensor ensures that your biometric information is secure and never leaves your device. As part of our ongoing security development lifecycle, Pixel 6 and 6 Pro’s fingerprint unlock has been externally validated by security experts as a strong and secure biometric unlock mechanism meeting the Class 3 strength requirements defined in the Android 12 Compatibility Definition Document (CDD).
Phishing continues to be a huge attack vector, affecting everyone across different devices.
The Pixel 6 and Pixel 6 Pro introduce new anti-phishing protections. Built-in protections automatically scan for potential threats from phone calls, text messages, emails, and links sent through apps, notifying you if there’s a potential problem.
Users are also now better protected against bad apps by enhancements to our on-device detection capabilities within Google Play Protect. Since its launch in 2017, Google Play Protect has provided the ability to detect malicious applications even when the device is offline. The Pixel 6 and Pixel 6 Pro uses new machine learning models that improve the detection of malware in Google Play Protect. The detection runs on your Pixel, and uses a privacy preserving technology called federated analytics to discover commonly-run bad apps. This will help to further protect over 3 billion users by improving Google Play Protect, which already analyzes over 100 billion apps every day to detect threats.
Many of Pixel’s privacy-preserving features run inside Private Compute Core, an open source sandbox isolated from the rest of the operating system and apps. Our open source Private Compute Services manages network communication for these features, and uses federated learning, federated analytics, and private information retrieval to improve features while preserving privacy. Some features already running on Private Compute Core include Live Caption, Now Playing, and Smart Reply suggestions.
Google Binary Transparency (GBT) is the newest addition to our open and verifiable security infrastructure, providing a new layer of software integrity for your device. Building on the principles pioneered by Certificate Transparency, GBT helps ensure your Pixel is only running verified OS software. It works by using append-only logs to store signed hashes of the system images. The logs are public and can be used to verify that what’s published is the same as what’s on the device – giving users and researchers the ability to independently verify OS integrity for the first time.
Beyond the Phone
Defense-in-depth isn’t just a matter of hardware and software layers. Security is a rigorous process. Pixel 6 and Pixel 6 Pro benefit from in-depth design and architecture reviews, memory-safe rewrites to security critical code, static analysis, formal verification of source code, fuzzing of critical components, and red-teaming, including with external security labs to pen-test our devices. Pixel is also part of the Android Vulnerability Rewards Program, which paid out $1.75 million last year, creating a valuable feedback loop between us and the security research community and, most importantly, helping us keep our users safe.
Capping off this combined hardware and software security system, is the Titan Backup Architecture, which gives your Pixel a secure foot in the cloud. Launched in 2018, the combination of Android’s Backup Service and Google Cloud’s Titan Technology means that backed-up application data can only be decrypted by a randomly generated key that isn't known to anyone besides the client, including Google. This end-to-end service was independently audited by a third party security lab to ensure no one can access a user's backed-up application data without specifically knowing their passcode.
To top it all off, this end-to-end security from the hardware across the software to the data center comes with no fewer than 5 years of guaranteed Android security updates on Pixel 6 and Pixel 6 Pro devices from the date they launch in the US. This is an important commitment for the industry, and we hope that other smartphone manufacturers broaden this trend.
Together, our secure chipset, software and processes make Pixel 6 and Pixel 6 Pro the most secure Pixel phone yet.
