I'm also having the same issue. I am 100% positive that I'm using the correct email and password for the game (not the forum account). I know these are the correct credentials because they were working a few months ago. I wasn't able to play until today but now I'm locked out of my account. It sucks because I love this game wholeheartedly, but something needs to be done about it refusing to allow you to log back in. I shouldn't have to make a support ticket just because I can't log in and the password reset request won't go through my email. 2FA would be wonderful for something like this, and I'm a bit miffed something like it hasn't been added yet. Even having a prompt on your forum account saying "yes this is my game account and I would like to log back in" would be super helpful.
