Reactivate Duo Push


NEW Universal Prompt Login Experiences! Effective March 26, 2024, Campus IT Services and Health Information Services will jointly upgrade to Duo's new Universal Prompt login experience. The upgrade will change the login visuals and process.


If you get a new phone to use with the same number you have previously used with Two-Step login, follow this reactivation process. The following steps can also be used if your Duo app no longer works. If your app asks for a new QR code or a re-activation link, the following steps will re-activate your Duo app. 

Critical Concepts

Steps to Take

  1. Go to the two-step login device management page (; log in with your Active Directory credentials.
  2. Complete two-step login process by selecting the Enter a Passcode button. Since your upgraded phone has the same number, you should be able to perform two-step with text passcode or a token code.

    • Select the Device Options button. Make sure the number you see matches the number of your new phone.
  3. Enter the passcode you have from either your text or token. If you do not have text passcodes readily available, you can receive a text with your passcodes by pressing the “Text me new codes” button on the bottom blue message.
