I can no longer log in because of the two-factor authentication, what should I do?

If you no longer have the device on which the code is generated that you need for the two-step authentication, this means that you will have to temporarily deactivate this additional security measure in order to be able to log back into your account. To do this, you can contact our customer service by phone. Once you have deactivated the two-step authentication, you can log in with your username and password. If you wish, you can then reactivate the two-step authentication via the "Personal settings" in your profile.
