## What it is
A minimal forward authentication service that adds Google/OpenID Connect OAuth-based SSO login in front of any HTTP service behind the Traefik reverse proxy. It supports multiple providers, multiple domains, rule-based selective authentication, and deploys via Docker or Kubernetes.

## Use cases
- add google oauth login to services behind traefik
- protect self-hosted apps with sso
- forward auth middleware for traefik
- add openid connect authentication to internal apps
- require login before accessing docker swarm services
- centralized authentication for multiple subdomains

## When to choose
- you use Traefik as your reverse proxy and want OAuth/SSO protection for backend services
- you need multi-provider (Google, OIDC) login with multi-domain support
- you want a lightweight, minimal alternative to oauth2-proxy

## When to avoid
- you don't use Traefik or a reverse proxy that supports forward auth
- you need full-featured identity management like user provisioning or MFA flows
- you need providers beyond Google/OIDC such as SAML

## Facets
- artifact type: service
- maturity: active
- function: auth, middleware, http-server, security
- domain: security, self-hosted, web-development
