If you incorrectly enter your password too many times in a row, then you get that message. So, the only thing you can do is just wait.

Where are you incorrectly entering your password? If it's on the login screen of the game, you should be disabling Key Maps (Shift Alt M) when entering it, so that your Key Maps don't conflict.
