Just got the game and it won't let me past the 2 part authenticator. It says you can disable it, but there is no button to do that. I had this on my XBOX and it was pretty fun, but wanted to play on a computer, and if you have to go through this much hell to play a game, its not really worth it to me.
Sorry you're running into the issue. I'm not sure how much help I'll be with this, since this is more related to your account rather than the game. We have a team on hand to help with any account issues though. They'll likely need some more info. Can you reach out to them over at http://support.ubi.com?
