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
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).
navigator.credentials.create() calls made with a non-empty
allowCredentials properties, the returned
userHandle may be null.
