Alternative initial registration in Cisco Duo via a mobile device

Before you can use Cisco Duo and thus multi-factor authentication, you must first register a second factor.

Prerequisites

To use the Duo Mobile app as a second factor, you need a mobile device - typically a smartphone or tablet - that meets one of the following requirements:

  • Android 11 or higher
  • iOS 15.0 or higher
  • iPadOS 15.0 or higher
  • watchOS 4.0 or higher

You can find more details on the requirements for Android here and for iOS (iPhone/iPad) here.
Please note that a screen lock (e.g. PIN, password, fingerprint, etc.) must be set up on the mobile device used. Otherwise, authentication attempts will be rejected. Mobile devices from Huawei are not supported.

If you do not have a mobile device compatible with these requirements, please contact the RRZK Helpdesk.

You will now need to install the "Duo Mobile" app on your mobile device for the next steps (see requirements). You can find the app in the respective play or app stores.
