            credential_id: "",
            key_type: "",
            key_algorithm: "",
            key_curve: "",
            key_value: "",
            rp_id: "",
            user_handle: None,
            user_name: None,
            counter: "",
            rp_name: None,
            user_display_name: None,
            discoverable: "",
            creation_date: 1970-01-01T00:00:00Z,
        }
