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 or Traefik by handling forwarded authentication and authorization requests.

BREAKING NEWS: Authelia v4 release is coming soon! The new version is written in Go for reliability, performance and security improvements.
It is currently available in beta in master.
Please read AUTHELIA-V4.md if you want to migrate from v3 to v4. But note that the data model migration is not automated yet.

Authelia can be installed as a standalone service using Docker or NPM but can also be deployed easily on Kubernetes leveraging ingress controllers and ingress configuration.
