Duo - Get a Temporary Access Code


  • How do I generate a temporary Duo access code?


  • Oregon State University
  • Employee, Student or Associate
  • ONID Account
  • Duo user


If you have just one Duo device (e.g., phone or hardware token) there may be some situations where it's helpful or reassuring to have a temporary backup access code for Duo. A temporary access code will allow you to complete a Duo authentication even if your primary Duo device isn't available.  Some situations might be:

  • Your current Duo device is unreliable (e.g., failing battery).
  • You're planning to replace your only Duo device, and need a way to activate your new device.
  • You have important work to do outside of business hours.

You can generate a 24-hour Duo code in advance of these activities as a "backup" to your regular Duo device.

Please note:

  • This code will be valid for unlimited uses for 24 hours
  • The code must be generated in advance of the planned need -- a Duo authentication is needed to generate this code.
  • We recommend having a second Duo device (hardware token or mobile device).

Generate a 24-hour Duo code

  1. Go to duo.oregonstate.edu. Scroll down and click the button labeled "Generate a temporary code."
  2. You will need to login and authenticate with Duo.
  3. You will see the following screen:

  1. Click the orange "Generate Temporary Duo Code" button.
  2. You will see a screen with your code and the expiration date/time.


For assistance with Duo, please contact your department's IT Helpdesk, or the IS Service Desk
