What is Authelia?

Editorial review

Authelia provides authentication, single sign-on, and access control you can self-host. Add 2FA, SSO, and fine-grained permissions to applications that don't have them, all running on your infrastructure. The reverse proxy integration model means existing applications don't need modification. Policies control who can access what based on users, groups, and network conditions. Teams who need enterprise-grade identity features without cloud dependencies deploy Authelia as their authentication layer.
