Getting A New Smartphone Or Tablet On Black Friday?

Do you have your eye on a new smartphone or tablet in the Black Friday (or Cyber Monday) sales? Follow these steps to enroll your new device in multi-factor authentication (MFA-Duo)—so you can “Prove It’s You” and protect your personal online identity, as well as help safeguard UW–Madison’s digital assets.

Don’t Have Another Device Set Up in MFA-Duo?

If you are currently unable to log in to MFA-Duo because you do not have another device set up already, or you do not have a saved list of backup codes, you will need to use a temporary passcode to log in (see MFA-Duo – Request a Temporary Passcode).

If you are able to log into MFA-Duo with a previously registered device or backup passcode, you can skip this step and follow the steps below.

Already Have an MFA-Registered Device?

  1. Navigate to the UW–Madison MFA Portal at MFA.wisc.edu and log in with your NetID and password if requested.
  2. Once there, click Manage MFA Preferences and Devices.
  3. Follow the steps in the Reactivate Duo on a Mobile Device KnowledgeBase article to set up your new phone or tablet.

Don’t Forget: Create Backup Codes

While you’re in the MFA Portal, it’s always a good idea to generate a list of backup passcodes for future use, in case you misplace your phone, or you find yourself in a situation where you can’t bring in your MFA-registered device (such as a secured location or a classroom where you’re taking a test and can’t have any devices). See Generating Backup Passcodes for Future Use.

Remember: Backup passcodes should be stored offline in a secure place, and they expire after four months.
