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.

1. Welcome Screen

When you first attempt to activate on a Duo-protected website, you will be presented with a Welcome and start Set Up screen for enrolling in Duo.  Click on the green Start Setup button to begin the enrollment process.

2. Choose Primary Device for Authentication

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.)

3. 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 with you when you’re logging into the Florida Tech CAS service.
3. Verify that you have entered the number correctly, check the box and click Continue.

4. Choose Device Platform

Choose your device’s operating system and click Continue.

5. Install Duo Mobile

1. Launch the App Store on your mobile phone.

2. Get the Duo Mobile App and install it.

3. Tap "OK" when asked if Duo Mobile should be able to send push notifications.

6. Activate Duo Mobile

Activating the app links it to your account so you can use it for authentication.  Follow the platform-specific instructions on the screen

Activation Success!

The Continue button will be clickable and have a green check on it after you scan the barcode successfully.  Click Continue to go on. Then follow the prompts on your smartphone and computer to complete the process of linking your smartphone to your account.

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