How to deactivate 2FA Security?

If you get a new phone or you wish to activate your 2FA codes on a new device, you have to deactivate your current 2FA (two-factor authentication) security first. To deactivate your current 2FA settings, go to Settings -> Account.

Insert your current 2FA code and click the "Deactivate" button.

Now you can delete the current 2FA code in your Authenticator app and register a new code with the new phone or app.
