Step Two: Choose Your Authentication Device Type

Select the type of device to enrol and click Continue. We recommend using Mobile Phone or Tablet.

Step Three: Type Your Phone Number

Select your country from the drop-down list and type your phone number. Use the number of your smartphone, landline, or cell phone that you’ll have with you when you’re logging in to a Duo-protected service. You can enter an extension if you chose “Landline” in the previous step.

Double-check that you entered it correctly, check the box, and click Continue.

If you’re enrolling a tablet you aren’t prompted to enter a phone number.

Step Four: Choose Platform

Choose your device’s operating system and click Continue.

Step Five: Install Duo Mobile

Follow the platform-specific instructions on the screen to install Duo Mobile. After installing our app return to the enrolment window and click I have Duo Mobile installed.

Step Six: Activate Duo Mobile

Activating the app links it to your account so you can use it for authentication.

On iPhone, Android, and Windows Phone activate Duo Mobile by scanning the barcode with the app’s built-in barcode scanner. Follow the platform specific instructions for your device:

The “Continue” button is clickable after you scan the barcode successfully.


Your device is ready to approve Duo push authentication requests. Click Send me a Push to give it a try. All you need to do is tap Approve on the Duo login request received at your phone.
