      Authelia is an open-source authentication and authorization server
      providing two-factor authentication and single sign-on (SSO) for your
      applications via a web portal. It acts as a companion for reverse proxies
      like nginx, Traefik, caddy or HAProxy to let them know whether requests
      should either be allowed or redirected to Authelia's portal for
      authentication.
