How to generate passcodes with the Duo Mobile app


This article explains how to generate two-step login passcodes using the Duo Mobile app by Duo Security and store them for future use.

Passcodes can provide a backup in case your other registered device(s) are unavailable.



Install the Duo Mobile app on your smartphone. (Apple Store) (Google Play)

How to Generate Passcodes

Follow these instructions to generate passcodes:

  1. Open the Duo Mobile app on your cellphone.
  2. Tap on the “DUO-PROTECTED University of Oregon” entry (shown below).
  3. Use the passcode during login (instructions below), or if you'd like to save it for later use, write it down instead.
  4. To generate multiple passcodes, click on the blue refresh icon to the right of the displayed passcode, and a new six-digit passcode will appear each time; repeat to generate as many additional passcodes as required. When generating more than one passcode, be sure to write them down in the order they are created.

How to Use Passcodes for Two-Step Login

  • Click the "Enter a Passcode" button on the two-step login prompt
  • Type in the passcode digits
  • Click Log In

How to Securely Store Passcodes

Keep passcodes somewhere safe from prying eyes, like in your wallet, or in an encrypted password safe application.

Avoid storing your Duck ID password or details about how to use these passcodes near where you keep the passcodes themselves.

Passcode Tips

  • Passcodes can serve as a backup in case your other registered devices become unavailable.
  • Each passcode can only be used one time.
  • Use your passcodes in the order they were generated.
  • The passcodes do not have an expiration date. However, when you use a passcode, all passcodes you generated before that one become invalid for future use.
