How to Generate Passcodes
Follow these instructions to generate passcodes:
- Open the Duo Mobile app on your cell phone.
- Tap on the University of Oregon entry.
- Use the passcode during login, or if you'd like to save it for later use, write it down instead.
- To generate multiple passcodes, click on the Refresh Passcode button below the displayed passcode, and a new six-digit passcode will appear each time; repeat to generate as many additional passcodes as required.
Note: When generating more than one passcode, be sure to write them down in the order they are created.
How to Use Duo Mobile passcodes for Two-Step Login

- For the Duo Mobile app, select the Duo Mobile passcode option
- Type in the passcode digits
- Click Log In
How to securely store passcodes

- 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.
- If you use a passcode out of order, any preceding ones will be invalidated.
- Passcodes can be generated without cellular data or Wi-Fi connection.
- 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.
