Signal doesn’t come with authentication support by default, but as it is a Rails application, is very easy to extend its functionality with a plugin.

We at Gonow started using Signal with Gitorious in a intranet and as we trust each other, authentication was not a problem. As time passed by, we changed Gitorious for Github, so we exposed our server to the internet and as some projects must stay secret, we needed a way to secure them and this way signal-auth was born.

As a Signal plugin is nothing more than a Rails plugin, the installation is like any other:

script/plugin install git://github.com/dcrec1/signal-auth.git

After this, you only need to customize config/signal-auth.yml with your desired user and password.
