How to remove facebook connect

When a user logs in there is a Auth type dropdown field with basic and facebook connect. How do I remove this?

tools-modules uninstall it

So if I uninstall the store, it looks like I can reinstall down the road, am I correct or no. Thanks

Totally unrelated question to this topic, but yes, if you uninstall a module, you can always re-install it later.
