Two-factor authentication

Why should I set up 2FA?

Do you have concerns about cybersecurity? Would you like to boost the protection of your GMX email account? Have you heard about the security benefits of two-factor authentication, also known as 2FA, and wondered if it is for you?

This two-step verification process has several benefits:

  • Even if your password should fall into the wrong hands, no one can log in to your email account without a time-based one-time password generated by an authenticator app on your smartphone.
  • Once you have enabled 2FA, you use it not only to log in to your email account on your computer, but also the GMX Mail App and GMX MailCheck – for better protection everywhere.
  • The security of GMX two-factor authentication extends to your associated email accounts, online calendars and address books, like Outlook and CalDAV.

How does two-factor authentication work?

Web browser

When you log in to your GMX email account in your computer’s web browser, in addition to your password you must enter a 6-digit security code each time. You generate this code on your smartphone using a separate authentication app.

GMX Mail App

When you activate 2FA, you will initially be logged out of your GMX Mail App. To log back in to the app, you need your password and a one-time 6-digit security code generated using a separate authentication app. You only have to do this once.

Third-party email programs

If you retrieve your emails via POP3/IMAP using an external email program such as Outlook or Thunderbird, you will be asked to enter an application-specific password once in your email program when you activate two-factor authentication.

How to generate a one-time password

2FA is a multifactor authentication process, with the second factor provided by an OTP (one-time password) app on your smartphone. This separate authentication app generates a six-digit security code for you to enter when using the two-factor authorisation. Therefore, you will need your smartphone and the app each time you log in to your email account on your computer as well as the first time you log in to the GMX Mail App after activating 2FA.

This means that if you do not have one already, you will have to install a free authenticator app on your smartphone in order to use 2FA. Once installed, such apps also work without a connection to a mobile network. Please see our GMX Help Center if you are not sure which authenticator app to use – we have put together a list for you.
