In this video, I will demo how to enable and deactivate two-factor authentication for your activation / call of duty account.
It is straightforward, and you get backup codes when you set this up, this allows you to log in using the backup codes if for some reason you can’t log in using the Google authenticator.
I will be doing a new video on Google authenticator and what you need to do to recover it if it is lost soon!
Update :
If you are having issues enabling your 2fa on Activision, try the steps shown below.
