Authelia - The Single Sign-On Multi-Factor Portal For Web Apps

Authelia – The Single Sign-On Multi-Factor Portal For Web Apps

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.
Documentation is available at https://docs.authelia.com.

Authelia can be installed as a standalone service from the AUR, using a Static binary, Docker or can also be deployed easily on Kubernetes leveraging ingress controllers and ingress configuration.

Here is what Authelia’s portal looks like

Proxy support
Authelia works in combination with nginx, Traefik or HAProxy. It can be deployed on bare metal with Docker or on top of Kubernetes.

Getting Started
You can start utilising Authelia with the provided docker-compose bundles:

Local
The Local compose bundle is intended to test Authelia without worrying about configuration. It’s meant to be used for scenarios where the server is not be exposed to the internet. Domains will be defined in the local hosts file and self-signed certificates will be utilised.

Lite
The Lite compose bundle is intended for scenarios where the server will be exposed to the internet, domains and DNS will need to be setup accordingly and certificates will be generated through LetsEncrypt. The Lite element refers to minimal external dependencies; File based user storage, SQLite based configuration storage. In this configuration, the service will not scale well.

Full
The Full compose bundle is intended for scenarios where the server will be exposed to the internet, domains and DNS will need to be setup accordingly and certificates will be generated through LetsEncrypt. The Full element refers to a scalable setup which includes external dependencies; LDAP based user storage, Database based configuration storage (MariaDB, MySQL or Postgres).

Deployment
Now that you have tested Authelia and you want to try it out in your own infrastructure, you can learn how to deploy and use it with Deployment. This guide will show you how to deploy it on bare metal as well as on Kubernetes.
