Hi, i have a client that would like to have their user be able to log-in to their site using their Facebook accounts. This part is simple, the complication is how to limit whom can log-in. I tried to find a way to simply replace the WP log-in for existing users and allow them to use their Facebook accounts.
So is there a way to connect existing user account to their respective Facebook accounts requiring only a one time WP user registration ?
The key is limiting who can access the site yet allow for Facebook log-in. Thank you for help.
