AuthenticatorAssertionResponse: userHandle property
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The userHandle
read-only property of the AuthenticatorAssertionResponse
interface is an ArrayBuffer
object providing an opaque identifier for the given user. Such an identifier can be used by the relying party's server to link the user account with its corresponding credentials and other data.
This value is specified as user.id
in the options passed to the originating navigator.credentials.create()
call.
Value
An ArrayBuffer
object representing an identifier for the current user. This is not intended to be human-readable. The relying party should make sure that the user.id
passed into the originating create()
call does not contain any personally identifying information (for example user name, email, or phone number).
For navigator.credentials.create()
calls made with a non-empty allowCredentials
properties, the returned userHandle
may be null.
Examples
See User login using the WebAuthn API for a detailed example.
