DUO has migrated from their traditional authentication window to what they now call the Universal Prompt. Please visit the DUO Universal Prompt article for more information.

The steps below will walk you through the setup and process for using DUO. The setup must be completed on a computer and you will need to have access to a smartphone and
other devices* you will be using to complete your authentication.

*The Office of Information Technology (OIT) recommends using a smartphone as the primary device and a landline as your optional secondary device.

Choose Primary Device for Authentication

1. Select the type of device you’d like to enroll and click Continue. (A smartphone is recommended for your primary device, with a landline as a backup.)

Enter Your Phone Number

1. Select your country from the drop-down menu (the U.S. is the default.)
2. Use the number of the smartphone landline, landline or cell phone you will most likely have when logging into the Florida Tech CAS service.

IT recommends adding your landline in case you lose or do not have your smartphone with you.
