PublicKeyCredential: rawId property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The rawId read-only property of the
PublicKeyCredential interface is an ArrayBuffer object
containing the identifier of the credentials.
The PublicKeyCredential.id property is a base64url encoded version of this identifier.
Note:
This property may only be used in top-level contexts and will
not be available in an <iframe> for example.
Value
A ArrayBuffer containing the identifier of the credentials. This
identifier is expected to be globally unique and is appointed for the current
PublicKeyCredential and its associated
AuthenticatorAssertionResponse.
