The FIDO 2 proposals present a strong user authentication framework that can replace passwords and will achieve it without compromising user convenience and experiences across different types of devices and clients. This document is an overview of the set of FIDo 2 specifications and is a recommended first-read before reading the individual specifications. Other documents may supersede this document. This is a Review Draft Specification and is not intended to be a basis for any implementations as the Specification may change. It must provide a cryptographic proof (i.e.e., attestation) of the nature of the credentials used. It must improve usability compared to passwords.”]
