Requesting a Temporary Passcode

Should you lose, misplace, or forget your MFA device and cannot authenticate, you can request a temporary passcode. These can also be requested if you are going to a testing center and will not have access to your device.

  • Passcodes are good for 3 days or 100 uses, whichever comes first. You can request 24 passcodes per year, so these should not be relied upon as a primary authentication method.

The instructions below assume that you know your password. If you do not know your password, please contact Technology Solutions.

Request a passcode in advance (you currently have your device)

  1. Visit the NetID Center.
  2. Select Temporary Passcode at the bottom of the page.

    If you do not have recovery options set up or cannot access your recovery options, you will need to call Technology Solutions Service Desk at 312-413-0003 to receive a temporary passcode.

    Once you receive a temporary passcode, please visit https://identity.uillinois.edu to set up your recovery email under the Recovery Settings.

    For instructions on setting up recovery options, see NetID Center, Set and modify your recovery options.

Using a Temporary Passcode

  1. Go to the application you are trying to access that requires MFA and login with your NetID and password.
  2. Select the Bypass code option.
  3. Enter the code and select Verify.

Canceling a Temporary Passcode

  1. Visit the NetID Center at https://identity.uillinois.edu, select Manage my 2FA under 2-Factor Authentication
  2. Under My Devices & Settings select the next to Temporary Passcode and then the trash can to delete/expire the code.
