Authelia is an open-source authentication and authorization server providing 2-factor authentication and single sign-on (SSO) for your applications via a web portal. It acts as a companion of reverse proxies like nginx, Traefik or HAProxy to let them know whether queries should pass through. Unauthenticated user are redirected to Authelia Sign-in portal instead.
The architecture is shown in the diagram below.
