Authelia
Authelia is a complete HTTP 2-factor authentication server for proxies like nginx. It has been made to work with NGINX auth_request module and is currently used in production to secure internal services in a small docker swarm cluster.
Features
- Two-factor authentication using either TOTP - Time-Base One Time password - or U2F - Universal 2-Factor - as 2nd factor.
- Password reset with identity verification by sending links to user email address.
- Access restriction after too many authentication attempts.
Deployment
If you don't have any LDAP and nginx setup yet, I advise you to follow the Getting Started. That way, you will not require anything to start.
Otherwise here are the available steps to deploy on your machine.
With NPM
npm install -g authelia
With Docker
docker pull clems4ever/authelia
Getting started
The provided example is docker-based so that you can deploy and test it very quickly. First clone the repo make sure you don't have anything listening on port 8080 before starting. Add the following lines to your /etc/hosts to simulate multiple subdomains
127.0.0.1 secret.test.local
127.0.0.1 secret1.test.local
127.0.0.1 secret2.test.local
127.0.0.1 auth.test.local
Then, type the following command to build and deploy the services:
docker-compose build
docker-compose up -d
After few seconds the services should be running and you should be able to visit https://localhost:8080/.
Normally, a self-signed certificate exception should appear, it has to be accepted before getting to the login page:
1st factor: LDAP
An LDAP server has been deployed for you with the following credentials: user/password.
Type them in the login page and validate. Then, the second factor page should have appeared as shown below.
2nd factor: TOTP (Time-Base One Time Password)
In Authelia, you need to register a per user TOTP secret before authenticating. To do that, you need to click on the register button. It will send a link to the user email address. Since this is an example, no email will be sent, the link is rather delivered in the file ./notifications/notification.txt. Paste the link in your browser and you'll get your secret in QRCode and Base32 formats. You can use Google Authenticator to store them and get the generated tokens required during authentication.
2nd factor: U2F (Universal 2-Factor) with security keys
Authelia also offers authentication using U2F devices like Yubikey USB security keys. U2F is one of the most secure authentication protocol and is already available for accounts on Google, Facebook, Github and more.
Like TOTP, U2F requires you register your security key before authenticating with it. To do so, click on the register button. This will send a link to the user email address. Since this is an example, no email will be sent, the link is rather delivered in the file ./notifications/notification.txt. Paste the link in your browser and you'll be asking to touch the token of your device to register it. You can now authenticate using your U2F device by simply touching the token.
Password reset
With Authelia, you can also reset your password in no time. Click on the according button in the login page, provide the username of the user requiring a password reset and Authelia will send an email with an link to the user email address. For the sake of the example, the email is delivered in the file ./notifications/notification.txt. Paste the link in your browser and you should be able to reset the password.
