How to use the DUO Mobile app to generate a passcode

Instructions on how to use the DUO Mobile app on your phone to generate a passcode.

A passcode can be generated by using the Duo Mobile app on your smartphone or tablet. The app can generate passcodes you can use to login when you do not have a cellular or WiFi connection and even when your device is in airplane mode.

  1. Open the Duo Mobile app on your device. 

  2. In the app, tap the UW-Parkside account.

Important: If the passcode fails, the DUO Mobile app may be out of sync. The Duo Mobile app can generate approximately 20 passcodes without successfully authenticating with Duo before re-synchronization is needed. Resynchronization may be needed because the server's counter value is only incremented after a successful authentication whereas the counter on the remote device is incremented every time a new passcode is requested by the user. Because of this inconsistency, the counter values on the server and in the app be out of synchronization. 

How to Re-Sync DUO Mobile:

  • Enter three consecutive and correct passcodes from the Duo Mobile app in three successive authentication attempts within 5 minutes
  • The first two authentications will fail, however the  passcodes will resynchronize and the third authentication should succeed.
