FIDO2 (Fast Identity Online) extends FIDO U2F to provide support for passwordless and multi-factor authentication.
It combines the capabilities of Web Authentication (WebAuthn) with Client-To-Authenticator-Protocol (CTAP) to bring FIDO2 to devices and browsers.
FIDO2 enables authentication methods to be verified by a physical security key such as a Yubikey or using built-in platform authenticators such a fingerprint readers and web cameras.
Implementations and supported platforms include:
- Windows Hello - provides support for authentication using fingerprints or facial recognition.
- iOS 13.3 and above - adds support for NFC, USB, and Lightning FIDO2-compliant security keys in Safari.
- Android - native apps.
- Browsers - includes Edge, Firefox, Chrome, Safari and Opera.
