authelia

![license][Apache 2.0]

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.

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.

Here is what Authelia's portal looks like
