I’ve seen a lot of people complaining about Battlefield 3 using your Origin ID. If you set your Origin ID before realizing what it was going to be used for it is actually pretty easy to change if you have an iOS device.
Simply download Scrabble Free for iOS and then log in with your Origin account. Once you’ve logged in go to settings (the little gear in the bottom left corner) and then click on “Edit Account” and there you go. You can change your username to something you are more comfortable with
