Authentication error is pretty common, usually happens when you try to re-enter the game. It usually goes away if you leave the game and launcher off for a few hours. Trying to log in before the wait is over can result in a long extension of your wait time, so give it a good few hours (at least 6) since your last attempt. If you still get the error after 24 hours of not attempting to log in then contact EA support.
