The key is to connect your Playstation Network ID with your EA Master Account.

1. Go to https://www.ea.com/profile/login.
2. Choose to sign in using your account with:PSN (Playstation Network).
3. Sign In with your PSN Id name or your PSN e-mail address and your PSN password.
If you don't yet have a EA Master account, then Create a new EA Master account.
4. When you open your EA account you must be sure that you verified your email address, otherwise you must verify your email address now.
