To deactivate Two-Factor Authentication (2FA), find the Account page on the left menu.
Click "Security" and switch off the Two Factor Authentication. You will be asked to enter the Google Authenticator Code to confirm the deactivation.
Your 2FA is now deactivated. Until the 2FA has been activated again, you’ll need to insert a code received as an SMS when logging in. Remember to remove the account on your Google Authenticator App. If you decide to activate 2FA again the Google Authenticator App will not use the same code as it did previously.
