## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: auth, security, cryptography, sdk
- domain: security, web-development, backend, apis
- platform: python, cross-platform
- tags: webauthn, fido2, passkeys, passwordless-authentication, server-side, web-server
