## What it is
SimpleWebAuthn is a collection of TypeScript-first libraries (@simplewebauthn/server and @simplewebauthn/browser) that simplify adding WebAuthn-based passkey authentication to websites. It is FIDO conformance-tested and runs on Node, Deno, Bun, Cloudflare Workers, and modern browsers.

## Use cases
- add passkey login to a website
- implement WebAuthn registration and authentication in Node
- replace passwords with FIDO2 credentials
- support biometric authentication in the browser
- add MFA with hardware security keys
- verify WebAuthn attestation and assertion responses server-side

## When to choose
- you want a simple, well-documented TypeScript library for WebAuthn/passkeys
- you need FIDO conformance-tested WebAuthn verification on Node or Deno
- you want to avoid hand-rolling WebAuthn ceremony parsing and verification

## When to avoid
- you need a full turnkey auth service with user management, sessions, and UI
- your stack is not JavaScript/TypeScript based
- you need WebAuthn support for platforms outside browsers and JS server runtimes

## Facets
- artifact type: library
- maturity: active
- function: auth, sdk, security
- domain: web-development, security, developer-tools
- platform: browser, bun, cross-platform
- tags: webauthn, passkeys, fido2, typescript, mfa, passwordless, nodejs, deno
