Authelia is an open-source authentication and authorization server providing two-factor authentication and single
sign-on (SSO) for your applications via a web portal. It acts as a companion for reverse proxies like nginx, Traefik
or HAProxy to let them know whether requests should either be allowed or redirected to Authelia's portal for
authentication.

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

The following is a simple diagram of the architecture:

Authelia can be installed as a standalone service from the AUR,
APT,
FreeBSD Ports, or using a
Static binary,
.deb package, Docker or Kubernetes either manually or via
the Helm Chart (beta) leveraging ingress controllers and ingress configurations.

Here is what Authelia's portal looks like:

Features summary

This is a list of the key features of Authelia:

• Several second factor methods:


• Security Key (U2F) with Yubikey.


• Time-based One-Time password
  with Google Authenticator.


• Mobile Push Notifications
  with Duo.


• Password reset with identity verification using email confirmation.


• Access restriction after too many invalid authentication attempts.


• Fine-grained access control using rules which match criteria like subdomain, user, user group membership, request uri,
  request method, and network.


• Choice between one-factor and two-factor policies per-rule.


• Support of basic authentication for endpoints protected by the one-factor policy.


• Highly available using a remote database and Redis as a highly available KV store.


• Compatible with Traefik out of the box using the
  ForwardAuth middleware.


• Curated configuration from LinuxServer via their
  Swag container as well as a
  guide.


• Kubernetes Support:


• Compatible with the ingress-nginx, the
  Traefik Kubernetes CRD, and the
  Traefik Kubernetes Ingress Kubernetes ingress
  controllers out of the box.


• Beta support for installing via Helm using our Charts.


• Beta support for OpenID Connect.

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.

Help Wanted: Assistance would be appreciated in getting Authelia working with
Caddy and Envoy.

Getting Started
docker-compose

The docker-compose bundles act as a starting point for anyone wanting to see Authelia in action. You will have to
customize them to your needs as they come with self-signed certificates.

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.

Security

Authelia takes security very seriously. If you discover a vulnerability in Authelia, please see our
Security Policy.

For more information about security related matters, please read
the documentation.

Contact Options

Several contact options exist for our community, the primary one being Matrix. These are in addition to
GitHub issues for creating a new issue.

[email protected] is also available but is strictly reserved for security related
matters.

Breaking changes

Since Authelia is still under active development, it is subject to breaking changes. It's recommended to pin a version
tag instead of using the latest tag and reading the release notes
before upgrading. This is where you will find information about breaking changes and what you should do to overcome
said changes.

Why Open Source?

You might wonder why Authelia is open source while it adds a great deal of security and user experience to your
infrastructure at zero cost. It is open source because we firmly believe that security should be available for all to
benefit in the face of the battlefield which is the Internet, with near zero effort.

Additionally, keeping the code open source is a way to leave it auditable by anyone who is willing to contribute. This
way, you can be confident that the product remains secure and does not act maliciously.

It's important to keep in mind Authelia is not directly exposed on the
Internet (your reverse proxies are) however, it's still the control plane for your internal security so take care of it!

Contribute
