I need to change my two factor authentication method, number or my number is not available.


If your registered two factor authentication method is not working, we can help you get another option set up.  Due to the sensitive nature of the information your two factor account gives you access to, there are special authentication steps that must be taken to ensure that we are only making a change to your two factor account for you and no one else.

Available to

All UW students, faculty, and staff.


If you have multiple devices enrolled, in your two factor account, you can simply authenticate with an alternative method and then manage your devices.

To manage your devices:

  1. Click on My Settings & Devices
  2. Confirm your identity by authenticating with one of your previously enrolled devices
  3. From the Settings window, you can identify a default device, as well as rename and delete devices

If you have a new phone number with the same number, please use these instructions to activate Duo on your new phone: https://uwyo.teamdynamix.com/TDClient/1940/Portal/KB/ArticleDet?ID=17429

If you only have one device enrolled and have gotten a new phone number, please click Request Help here, then we need to verify your identity over a Zoom Session. Zoom Sessions are typically scheduled during normal business hours, Monday through Friday 8 am - 3:30 pm. At the time of the Zoom Session, please have a photo ID with you.
