The SCLogin module is simply a standard Joomla module. You can set it up and configure it just like any other module in the Joomla Module Manager. For more information on customizing the output or common issues, see:
www.sourcecoast.com/sclogin/documentation/
In general, the SCLogin module is a standalone module. When paired with JFBConnect, there are additional features for showing the social login features. That's why we include it with JFBConnect, but there's not an interface to configure SCLogin within JFBConnect itself.
I hope that helps, but if you need more help, let us know what issues you're running into.
Thanks,
