Duo Second Factor Devices

Details

As part of the Duo enrollment process, you need to select which device you are going to use to receive codes from Duo. Devices can also be manually added by a Duo account administrator once you have enrolled. Users can self-service add a device or manage their devices to their Duo account independent of the enrollment process. See this article for instructions to Manage Devices:

Duo authentication can be used with landline phones, mobile phones with or without data, tablets that are assigned a mobile phone number,  and hardware tokens.

Duo works with all cell phones and landlines by supporting authentication via phone call and text messaging (SMS).

If you select a Landline or mobile phone when enrolling in Duo, when you try to authenticate to a system using Duo, the device you specified during Duo enrollment will ring. Answer the call and listen to the instructions to authenticate.

If you select to receive a text message (SMS) on a mobile phone when enrolling in Duo, when you try to authenticate to a system using Duo, the Duo Mobile app on the device you set up will automatically open and ask for you to approve the connection. If you don't have a cell connection at the time you need to authenticate, the Duo Mobile app can generate a one time code for you to enter.
