## What it is
Tinyauth is a lightweight, OpenID Certified™ authentication and authorization server written in Go, shipped as a single static binary. It works as an auth middleware for apps behind reverse proxies (Traefik, Nginx, Caddy) or as a standalone OIDC provider, with OAuth, LDAP, and TOTP 2FA support configured via environment variables.

## Use cases
- add login to self-hosted apps behind traefik
- self-hosted single sign-on for homelab
- lightweight openid connect provider
- protect apps with 2fa totp
- authenticate apps with ldap
- forward auth middleware for nginx and caddy

## When to choose
- you want dead-simple SSO for self-hosted services with minimal configuration
- you need a tiny, resource-light OIDC provider instead of Keycloak
- you use Traefik, Nginx, or Caddy and want forward-auth protection

## When to avoid
- you need extensive enterprise identity features, user management dashboards, or fine-grained RBAC
- you require long-term config stability, as configuration changes frequently between releases
- you need a full-featured identity platform with social login federation beyond basic OAuth/LDAP
