The W3C Web Authentication (WebAuthn) specification repository, defining a browser API for creating and using scoped, attested public key credentials for strong user authentication. It is a standards document (Level 3 editor's draft) rather than runnable software, maintained by the W3C WebAuthn Working Group.
Use cases
- implement passkey login in a web app
- understand how WebAuthn public key credentials work
- implement a FIDO2/WebAuthn relying party server
- contribute feedback on the WebAuthn Level 3 specification
- learn how authenticators and user agents mediate credential access
- look up normative requirements for passwordless authentication
When to choose
- you need the authoritative, normative definition of the WebAuthn API
- you are implementing a browser, authenticator, or server and need spec-level detail
- you want to track or contribute to the evolution of the standard
When to avoid
- you want a ready-to-use client or server library for WebAuthn
- you need a tutorial-style introduction rather than a formal specification
- you need a non-web (native mobile/desktop) authentication API
