Hi there, @RasSinOfGreed.
This can happen for multiple reasons. The first thing to do is update your password. Also, if there are too many repeated attempts at logging in, this message will come up. It should go away in about 90 minutes. Another possibility is that you're trying to log in with the wrong email address. If none of these are the case, try contacting @EAHelp through Twitter or open a case with a live support advisor here: https://help.ea.com/en/contact-us/new/. They'll look into this for you. Thanks!
