Duo Multi-Factor Authentication (MFA) Tips and Best Practices

Download Spare Passcodes

From Duo Mobile, download and store passcodes in a safe place such as a backpack, wallet, or purse. In the case of a drained or misplaced phone, you can use one of the codes to get access. Codes can only be used once, so we recommend downloading multiple codes at a time.

Enroll Multiple Devices

You can enroll multiple devices on your Duo account. We recommend that you add at least one secondary device such as the phone number of a trusted friend and/or family member. 

Use Push

The next time you're prompted by Duo, select "Send Me a Push." You will receive a notification on your device with the Duo app installed.  All you need to do is to tap on that notification, approve it and you’re in. The Duo app must be installed for Push to work.

Remember Me

On systems that require you to log in for every instance, you can have Duo remember you for up 10 hours.  To activate this, click the check box in front of "Remember me for 10 hours" next time you're prompted by Duo.

Traveling Internationally?

Why might Duo phone callback authentication fail to Chinese +86 numbers?

International students attending UND with a +86 country code (China) may also experience this issue.

Download spare passcodes.

Spare passcodes can be printed and saved for when needed.

Purchase a hardware token and enroll it before your trip.

Hardware tokens will allow you authentication without the need of your phone.
