AuthenticatorAttestationResponse extension type

The AuthenticatorAttestationResponse interface of the Web Authentication API is the result of a WebAuthn credential registration. It contains information about the credential that the server needs to perform WebAuthn assertions, such as its credential ID and public key.

An AuthenticatorAttestationResponse object instance is available in the PublicKeyCredential.response property of a PublicKeyCredential object returned by a successful CredentialsContainer.create call.

This interface inherits from AuthenticatorResponse.

Note: This interface is restricted to top-level contexts. Use of its features from within an iframe element will not have any effect.
