Couldn't something like needing a specific IP address for it be added, just like RC except the player can put in the IPs they want to be able to use the account.

You would ofcourse need a password to be able to edit the IPs that can be used. Could just set up something like the changing your actual password for that where you're sent e-mails to confirm it is your account.

That way if people use that the chance of other people getting on their account would be reduced.
