Setup Duo two-factor-authentication

Preamble

Another well known two-factor-authenticator is Duo. We strongly recommend setting up such a 2-Factor Authentication to protect your account. Please generate a recovery code afterwards so you always have a possibility to gain access to your account in case you lose your mobile.

Pre-requirements

Duo is a little bit more work to setup, as it has the precondition that you register for a Duo Account first on duo.com (opens new window).

During the registration process you are "forced" to download the "Duo Mobile" App, that you can get here for Android (opens new window) or here for Apple (opens new window)
