Duo - Generating a Passcode with a mobile device, works offline


How can I generate a passcode with my mobile device?  How do I use Duo on a cell phone that is offline?


  • Oregon State
    • Duo


You can always use your phone to generate a passcode to login with Duo.  This process works if your mobile device is offline with no cellular or wifi connection.

If your cell phone has no connection to the Internet you will not be able to receive a push notification from Duo on your phone. You can still generate a passcode form the Duo app in order to gain access to your account.


If you have automatic push enabled you must cancel the login request by clicking the “Cancel” button in the blue bar

  1. Click the “Enter a Passcode” button  
    enter a passcode
  2. In the Duo app on your mobile device tap the down arrow icon next to “Oregon State University”
  3. Type the 6 digit passcode shown into the Duo Authentication window and click “Log In”
    enter a passcode

Alternatively, you could get a Hardware Token in order to sign in without the need for a cell phone. 

For assistance with Duo, please contact your department IT team or the Service Desk.
