Question

How do I register multiple devices in Duo?

Answer

We recommend registering multiple devices in Duo because this will provide a backup method of authenticating with Duo when your primary method is not available.

If you have multiple devices registered in Duo, only the device that you select as your "Default Device" will receive the Duo prompt. You will not receive Duo prompts from every device each time you authenticate.

To enroll a secondary device:

1. Go to computingaccounts.ucdavis.edu
2. Select Duo Multifactor Device Manager
3. Authenticate with Duo
4. Select Add a device.

5. Now, follow the steps in one of the following articles to add a secondary device:

   2. Security Key
