Initial registration in Cisco Duo

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

Prerequisites

In order to carry out the following steps, you must be on the UoC campus with any computer (active WLAN or LAN connection to the UKLAN) in order to register once in Cisco Duo.

 

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. Authorization attempts from rooted devices will be rejected automatically. Mobile devices from Huawei are not supported.

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

Procedure

If you are setting up using a single mobile device, please follow these instructions:Initial registration of Cisco Duo with mobile device
