We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!

You need to have an EA account. That account needs to have the same email address as the one you have registered to your xbox account. You have to add a persona to your EA profile for the xbox account and when thats linked and you have the played game in
your games list you can log in to the battlelog!
