The FIDO2 set of specifications has two components: Web Authentication (WebAuthn) and Client-to-Authenticator Protocol 2 (CTAP2). The main component, WebAuthn, is a JavaScript API that is implemented in compliant web browsers and platforms so that registered devices can perform FIDO2 authentication.
FIDO authentication uses standard public key cryptography techniques to provide phishing-resistant authentication. During registration with an online service, the user’s client device creates a new cryptographic key pair that is bound to the web service domain.
FIDO (Fast Identity Online) is a set of technology-agnostic security specifications for strong authentication. FIDO is developed by the FIDO Alliance, a nonprofit organization that seeks to standardize authentication at the client and protocol layers.
FIDO (Fast IDentity Online) is an overarching term that includes many protocol specifications, including FIDO 1.0, FIDO2, FIDO UAF and FIDO U2F. To understand the difference between FIDO and FIDO2, it’s important to grasp the evolution of FIDO authentication.
Sep 27, 2023 · FIDO (Fast Identity Online) authentication refers to a set of specifications and standards created by the FIDO Alliance. It defines alternative authentication mechanisms that reduce reliance on passwords and enhance online security.
Based on FIDO standards, passkeys are a replacement for passwords that provide faster, easier, and more secure sign-ins to websites and apps across a user’s devices. Unlike passwords, passkeys are always strong and phishing-resistant. Access and utilize the FIDO trademark and service mark.
