Hi all,
When registering a WebAuthn credential using FaceID, in the fmt field of the returned AuthenticatorAttestationResponse.attestationObject, (as per section 8 (Defined Attestation Statement Formats) of the WebAuthn standards), has a value of "apple".
This is not registered in the IANA database (https://www.iana.org/assignments/webauthn/webauthn.xhtml), nor can I find a spec for this attestation format.
Could anyone direct me to the spec?
Thanks, Q
