[Plugin: Simple Facebook Connect] Existing Users Facebook Link

Nah, it’s easy.

1. Activate and setup the base SFC plugin.
2. Activate the SFC-Login plugin.
3. On every users “Users->Your Profile” page, there will be a new button that allows the user to connect their WordPress account to their Facebook Account. Tell them to click that and follow through with the instructions (nothing to it, really, just login to FB).
4. That’s it. Once they’re connected, it’ll change to showing them their photo, their name, and a new “Disconnect” button. As long as their account is connected, they’ll be able to login using the Connect with Facebook button on the normal wp-login screen.
