A Python 3 library implementing the server-side of the WebAuthn API for verifying FIDO2 credential registration and authentication. It supports all FIDO2-compliant authenticators including security keys, Touch ID, Face ID, Windows Hello, and Android biometrics.

Use cases

• add passkey login to a python web app
• verify webauthn registration responses server-side
• implement passwordless authentication with fido2 security keys
• support touch id or windows hello sign-in on my backend
• generate webauthn registration and authentication options
• verify attestation from a hardware security key

When to choose

• you need a focused, well-maintained Python library for WebAuthn server-side verification
• you want simple JSON-based integration between your backend and browser WebAuthn API calls
• you need support for all FIDO2-compliant authenticators including platform biometrics

When to avoid

• you need a full identity or SSO platform rather than a WebAuthn verification library
• your stack is not Python 3.10+
• you need client-side WebAuthn browser logic, which requires a separate frontend library
