[][Apache 2.0] [](https://travis-ci.org/clems4ever/authelia) [](https://snyk.io/test/github/clems4ever/authelia?targetFile=package.json) [](https://gitter.im/authelia/general?utm_source=share-link&utm_medium=link&utm_campaign=share-link) **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.

Here is what Authelia's portal looks like
