Duo: Add or Remove Devices

Duo Security is required for all students, faculty, and staff at the University of Minnesota. Duo adds an additional layer of protection to anything that requires your University internet ID for authentication. 

We strongly recommend adding at least two devices to your Duo account in case you cannot access your primary device for any reason. Plan ahead by generating bypass codes and enrolling a backup device so that you can always get into your account. If you cannot access your primary phone and have no bypass codes or backup devices, contact Technology Help.

Notes:

  • This article is for adding devices for active Duo accounts. If you need to enroll in Duo for the first time, read Enable Duo Security as a New User
  • If you have a new device with the same phone number, you will need to follow the instructions in Adding a New Device to Duo (in this article) to reconnect Duo after transferring your data to your new device.

You can enroll:

  • Smartphones and Tablets (Preferred)
  • Landlines and other Cellphones
  • Hardware Tokens
  • Security Keys (U2F Tokens)
  • Touch ID (requires Chrome)

Requesting a Hardware Token

To request a token, call Technology Help or visit a walk-in location with a valid ID. Tokens are free of charge. If your token dies or breaks, you may exchange it at a walk-in location. 

We recommend requesting a token only if you have a business need or if you cannot use Duo on other devices. 

If you are requesting a Hardware Token from an international location you will need to get your departmental supervisor's approval and contact Technology Help. The token will be sent to your departmental supervisor, who will be responsible for mailing it internationally. 

Notes: 

  • Requesting a Token from China: Please call Technology Help to start the process.
  • International students should purchase a U2F token or use another option

Removing a Device From Duo

There are various reasons you may wish to remove a device from your Duo account. You may need to remove a device no longer in use, either because you have a new device or because the device is lost or stolen.

To reduce security risk, make sure you remove lost or stolen devices from your account immediately. If your lost or stolen device is University-owned, report it to Technology Help as soon as possible.

Notes: 

  • While it is possible to remove a device from your Duo Device options, it is not possible to remove your account from Duo after opting in.
  • You can remove a device from Duo after adding a new device to your account or if you have a backup device connected.
  1. Using a computer, sign in to my-account.umn.edu with your UMN Internet ID and password.
  2. Authenticate with Duo using your backup device or bypass code.
    • Note: If you don't have a backup device or bypass codes, contact Technology Help.
  3. Select Duo Security from the navigation menu on the left-hand side of the page.
    1. Select Create or Manage Duo Account. You will need to authenticate using one of the options from step 2.
  4. Follow the instructions on Duo's website to Remove a Device
