!!! Overview[1][2]
[{$pagename}] is a [FIDO] [framework] of [specifications] designed to replace [passwords] with [credentials] that cannot be [phished|Phishing], replayed, or breached when servers are compromised – and to do that without sacrificing user convenience across difference types of devices and clients. 


To activate a [FIDO2] [credential] (e.g., on a security key) users can employ gestures such as the use of [PINs], [biometrics], or button-pushing. Once the user is [authenticated], the specifications enable the [authenticator] device (which could also be a host computer in its own right) to communicate information about the [authentication] event to other devices or systems using challenge/response protocols based on [Asymmetric Key Cryptography].

!! Core FIDO2 specifications 
* [FIDO] [Client To Authenticator Protocol] ([CTAP])
* [FIDO Web API|WebAuthN] ([WebAuthN])
* [FIDO Attestation|WebAuthn Attestation]: Defines attestation formats used to validate FIDO Authenticators, uses of FIDO 2.0 credentials, and associated user verification methods. FIDO attestation could be mapped as authentication context to federation servers or other conditional/adaptive authentication systems.


!! [{$pagename}] and related [specifications]
[{$pagename}] also leverages some related specifications: 
* Federation Protocol Profiles: These profiles (most still to be developed) will define how particular federation protocols can request and employ FIDO2 authentication and Token Bindings. An OpenID Connect FIDO profile is planned. Other profiles, such as a SAML 2.0 profile, are also possible.
* [Token Binding over HTTP] 
* [Token Binding Protocol] 

This landing page provides links to all FIDO2 specifications as well as the preceding FIDO UAF and U2F specs.
