Two-Factor Authentication Recovery Code

Two-Factor Authentication gives your 1&1 IONOS account additional security by requiring a special code during the login process. However, this code is only made available to the smartphone you assigned to the feature during the setup process. If you don't have your phone available when you need to log in, you can still log in using an alternative recovery code, which was provided to you when you set up Two-Factor Authentication. After you use the recovery code, you will then have to reinstall Two-Factor Authentication.

  • Enter your 1&1 IONOS Customer ID and recovery code here.
  • Log in to 1&1 IONOS.
  • After successfully logging in, you will need to set up Two-Factor Authentication again.
