A FIDO2-conformant WebAuthn and passkey backend library for Go applications. It implements the Web Authentication specification to enable multi-factor, passwordless, or usernameless authentication flows.

Use cases

• add passkey login to a Go web app
• implement passwordless authentication in Go
• add WebAuthn as a second factor
• verify FIDO2 authenticator registration and assertion responses
• support usernameless sign-in flows
• implement multi-factor authentication with hardware security keys

When to choose

• you are building a Go backend and need standards-conformant WebAuthn/passkey support
• you want FIDO2 conformance-tested authentication
• you need passwordless or MFA login without third-party auth services

When to avoid

• your backend is not written in Go
• you need a fully managed hosted authentication service
• you require a stable 1.x API since the library is still version 0 with possible breaking changes
