Heya @Blukid0610 ! I already answered this on another credential issue post, but felt the need to help you as well!
Because I had the same issue a few times after typing in my password wrong (by accident) and I got the credentials have expired issue, that prevented me from logging into my account. Apparently it's a very common bug, that occurs when you type in your password wrong... Super annoying.
I read somewhere else if you reset your password it works again, but be aware! I never got the email to reset my password. No matter how often I tried and I did not type my email address wrong! The email just did not come through.
Instead I tried what the other person already suggested and contacted an adviser (you can find it here: https://help.ea.com/en/contact-us/?product=origin).
They told me I get this issue because my account has not been verified yet. This is the instruction I got:
EA Account & Billing > Security > Login verification > Turn on > Answer security question > Select any of email/text/app authentication and it's all set.
I am not entirely sure if that was what solved it, (because he also send me a password reset that actually came through) but it helped for now. I was able to log in again.
So be careful when you type in your password, because if you make a mistake, you get this annoying problem xD Hope this helped in some way. Thought it was worth a try to let people know of this possible fix, since I haven't heard of this solution yet. At least now it's out there. Good luck xx
