## What it is
A security app and plugin for Caddy v2 providing authentication, authorization, and accounting (AAA). It supports Form-Based, Basic, Local, LDAP, OpenID Connect, OAuth 2.0, and SAML authentication, MFA/2FA, and JWT/PASETO-based request authorization.

## Use cases
- add single sign-on to a Caddy web server
- protect backend services behind OAuth2 or OpenID Connect login
- authorize HTTP requests with JWT or PASETO tokens
- enable MFA and YubiKey-based two-factor authentication
- integrate LDAP or SAML authentication with Caddy
- implement access control lists for web routes

## When to choose
- you already use Caddy v2 and want built-in AAA without a separate auth proxy
- you need multiple auth protocols (OIDC, OAuth2, SAML, LDAP) in one plugin
- you want token-based authorization with JWT or PASETO

## When to avoid
- you run nginx, Traefik, or another reverse proxy instead of Caddy
- you need a standalone identity provider rather than a gateway plugin
- you require extensive enterprise support or a large maintainer team
