IGN has changed randomly

Hmmmmmm.

Sounds fishy. Things like that do not change all by themselves. 

You say your account is fully secured. Are you sure? 

Have you ever let someone else use your account?

Are you the only one that can login to your account. No one else has your passwords login info?

Do you always logoff when finished playing on your account?

do you have 2FA enabled?

Read the tips below.

There are links for EA help and also if you think you have been hacked.

Account Safety

How to keep your account and hardware safe 101:

1. Use strong passwords for you game accounts. Keep track of your game account information (ownership) and to what other accounts they are connected to.
2. Use strong passwords for the associated E-mail account. Keep track of your E-mail accounts and what they are connected to.
3. Do not use e-mail accounts that you cannot fully control, like those provided to you through, schools, universities, workplace and or other organizations etc. If the Org. revokes your E-mail or you leave the school, switch workplace etc and no longer have access to that E-mail you will end up having issues you do not want or need.  
4. Do not share either of these passwords with others. Keep note of your passwords in a safe place.
5. Enable two factor identification for both the game and associated E-mail accounts.
6. Do not let others use your game account (Friends and family alike) because if they do something wrong on your account it is still your fault, nobody wants to have a sanction on their account because somebody else did or said something wrong.
7. Do not use internet café’s to access your account and play, you do not know what software is on the hardware there, you do not know if the hardware at the cafe has a hardware ban and this can affect your account in a negative way.
8. I would suggest only accessing your account with your own trusted hardware, gaming on another person’s hardware brings some of the same risks as above.
9. I would also suggest not letting others use your hardware in order to play with their account, because if they get a hardware ban on your hardware while using it, it can have a negative affect on your account.
10. Buying used hardware comes with risks as well. The hardware could have been banned and this is not an EA problem but a problem between the buyer and the seller. 
11. Play nice with others, in other words do not de-mean, harass or bully others in Chat or over voice coms, both can be reported and that can also have a negative effect on your account.
12. Use non-offensive user/gamer tag/club tags, if you get a warning about such change it, doing otherwise can lead to a negative effect on your account.
13. Play fair, boosting and teaming are cheating.
14. Play fair using cheating software or hardware is not fair and is really only cheating yourself.
15. Do not buy and or sell accounts, do you really know what has been done with the account? What cyber info are you giving up? What risk is there that the account is bunk. What is the risk to your hardware?
16. Re-read the Terms of Service agreement and the Terms of Sale agreement you agreed to play this game and adhere to it. https://www.ea.com/legal/user-agreement and https://www.ea.com/legal/terms-of-sale

About points 7, 8, and 9, I do know that not everyone can afford multiple hardware setups for the entire family and there is trust that has to be there, talking about the does and don’ts on the use of shared hardware should be done so everybody can enjoy what they do on the hardware and everyone can be safe.
