Where do I download an authentication app?

An authentication app will be required to set up two-factor authentication. It generates a unique, temporarily valid security code for each login process.

If you do not yet have an authentication app on your smartphone, you must first download or install one from the

Google Play Store or the Apple App Store.

For an overview of available free and paid apps as well as links to additional information, please visit Selection of apps for two-factor authentication.

If you already have an authentication app installed on your smartphone, then you can use it for two-factor authentication.

Click on Set up two-factor authentication for more information on the setup process.
