**http-two-factor** is the simplest to set up HTTP 2-factor authentication server. It is compatible with NGINX auth_request module and is used in production to secure internal services in a swarm cluster.

## Getting started

This project is docker-enabled so that you can deploy and test it very quickly. 
Before starting, make sure you don't have anything listening on port 8080. 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: http://localhost:8080/.

### LDAP authentication
An LDAP server has been deployed with the following credentials: **admin/password**.

### TOTP verification
You can use Google Authenticator for the verification of the TOTP token. You can either enter the base32 secret key or scan the QR code in Google Authenticator and the application should start generating verification tokens.

Test secret key: GRWGIJS6IRHVEODVNRCXCOBMJ5AGC6ZE

## Documentation
http-two-factor provides a way to log in using LDAP credentials and TOTP tokens. When the user is logged in,
the server generates a JSON web token with an expiry date that the user must keep in the *access_token* cookie.
