WebAuthn​ (Web Authentication), part of the FIDO2 Project, is a web standard published by the W3C that enables strong authentication with public-key cryptography, passwordless authentication, and secure two-factor authentication. The standard defines a JavaScript API which allows token registration and subsequent authentication. The API is implemented in current versions of all major browsers (​ Edge 18+, Firefox 60+, Chrome 67+, Safari 13+, Opera 54+​ ) and is also backwards-compatible with (legacy) U2F tokens.
