Last time we did a brief overview of the install for Authelia. Today, we'll be going a little deeper and going through each step together. We hope this helps make your installation a little easier.
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 users are redirected to Authelia Sign-in portal instead.
