Fixing Modern Warfare 2 2FA Authenticator Error

You are experiencing a 2FA authenticator error in Modern Warfare 2 because the game requires you to add your contact number to your Battle.net account.

The developers want to limit the number of free accounts so that they can reduce the number of cheaters and other players with toxic behavior.

Thus, fixing the authenticator error in MW 2 is pretty straightforward. Players only need to add their contact number to the Battle.net account or Steam. So, log into your account (Battle.net or Steam) and make sure your contact number is added or linked to the account details.

However, it is important to note here that you have to use your unique phone number for every account. This verification process may fail if you are using the same contact number on all accounts.

If you have already gone through this process and are still receiving the same error message then make sure you have entered the correct email address. Do this and you will be able to play the game without any issues.

That’s everything we have in this guide on how to fix Modern Warfare 2 2FA authenticator error.
