A Go server library implementing the WebAuthn (FIDO2) specification for adding passwordless authentication to web applications. It handles registration and login ceremonies with authenticators such as security keys and platform biometrics.

Use cases

• add webauthn passwordless login to a go web server
• implement fido2 security key authentication in go
• support passkey registration and login on my backend
• replace password authentication with hardware authenticators
• verify webauthn attestation and assertion responses in go
• build a u2f-compatible two-factor flow

When to choose

• you are maintaining a legacy Go project already built on this library
• you need a minimal, well-documented reference implementation of WebAuthn server logic in Go

When to avoid

• starting a new Go project - use the actively maintained go-webauthn/webauthn fork instead
• you need recent WebAuthn spec updates, bug fixes, or new authenticator support
• you need a client-side or non-Go implementation
