1. Enter a descriptive label for your device.

3. Follow instructions for setting up Duo Mobile. If you haven’t already installed the app on your device, install it now.

4. Open the Duo Mobile app and scan the QR code. (If you are working from the same mobile device you want to add, click the “Add Duo Account” button.)

5. Duo Mobile will create an account for your University of Iowa logins. Tap Save.

6. Click “Verify Duo Push” to send a push notification to Duo Mobile on the device you’re adding. Open Duo Mobile and tap the green “Approve” button.

7. You’ve now added a new mobile device and can select it from available options to verify your logins.

1. Log into the Account Center.

2. Look for “Backup Codes” on the main Two-Step Login with Duo page. Click “Generate Codes.”
    

   

    
    

3. Confirm you want to generate a new set of codes (it will invalidate any previous set).
    

   

    
    

4. You’ll see a set of 10 codes. Screenshot, copy, or write down the codes.
    

   

    
    

5. Click “Cancel” when finished or “Generate Codes” to create a new set.

The codes you’ve generated will work only with your HawkID and password. To use them, choose “Enter a Passcode” as your authentication method when completing a login. Enter any code from your set—each can be used just once.
