While working on a client site we realized that there is no simple plugin to connect users with Facebook. We needed a simple and non bloated solution that could scale if needed so we decided to build our own plugin.
If you are looking for a simple solution or you are a developer that needs a base plugin to let your users login or register with facebook this is your plugin.
As always you can go to WordPress repository to download the free Facebook Login plugin
