How to Activate or Reactivate Duo Mobile on a New Phone



If you have never installed the Duo mobile app on your smart phone or if you have recently purchased a new phone and kept the same number, you will need to install duo mobile and activate it. If you have a completely new number or cannot receive phone calls to two factor, please fill out the service form here.

The specific screens and options for this procedure can vary by device, browser, and previous account configuration.  If what you see in the procedure does now allow you to complete the steps, please call the UWIT Help Desk at 307-766-4357.


  1. It is recommended to complete the following steps through a browser on a computer with your phone for the Duo activation.  Start by opening an Incognito/Private window of your browser of choice.  This will allow access to the two factor screens even if you normally use the Remember for 14 days check box.

In Chrome:

In Firefox:

In Edge:

In Safari:

  1. Go to WyoSecure.  This process will look most consistent from this login. Complete the first step of authentication with your username and password.

  1. If your two factor is set up to automatically call you, you will need to cancel that call.  This will allow you to select your settings rather than enter WyoSecure.

  1. Click My Settings & Devices.

  1. To be able to change your settings and devices, you will need to two factor now.  You can two factor with a Yubikey or the Call Me option on this screen, even though phone calls will not be an option on other screens.

  1. You will see the phone that you have been receiving phone calls on listed.  Click the Device Options button next to it.

  1. Next click the Reactivate Duo Mobile button.

  1. You will get a question about the type of phone.  Select the correct radio button and click Continue.

  1. If you haven't installed Duo, please install the app, open the Duo app click I have Duo Mobile installed.

  1. Scan the QR code that shows on your computer screen with the Duo app.

  1. Now you can set Duo to automatically send a push when you authenticate.


Your Duo is now reactivated and you can use it to two factor.
