Single Sign-On Multi-Factor portal for web apps

<rendered-html><p>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.</p> </rendered-html>
