Deep dives
The Evolution of FIDO and WebAuthn
The podcast episode discusses the evolution of FIDO (Fast Identity Online) and WebAuthn (Web Authentication). FIDO was initially developed by Google and PayPal to eliminate passwords and enable biometric authentication on mobile devices. U2F (Universal Second Factor) authentication, where a security key is used as a second factor, became a part of FIDO. Eventually, U2F and the original FIDO standards merged to form Fido2, which is commonly referred to as Fido2. WebAuthn, part of the W3C (World Wide Web Consortium) standard, was developed to enable browser buy-in and facilitate the interaction between relying parties and web browsers. CTAP (Client to Authenticator Protocol) allows the browser to communicate with authenticators. FIDO authentication is now being integrated into various platforms, like Apple's Face ID, to offer passwordless login experiences.
