HTMLAnchorElement: username property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨January 2020⁩.

The username property of the HTMLAnchorElement interface is a string containing the username component of the <a> element's href. If the URL does not have a username, this property contains an empty string, "".

This property can be set to change the username of the URL. If the URL has no host or its scheme is file:, then setting this property has no effect.

The username is percent-encoded when setting but not percent-decoded when reading.

See URL.username for more information.
