Duo Security MFA: Adding or Changing an MFA Device

No longer have access to your old device?

If you need help activating a new device (like a new phone), but you no longer have access to a device that's enrolled in Duo Security MFA and associated with your account, you have two options available to restore your access to your Global ID account:
 

Option 1

Activate a new device using self-service options at https://myaccount.cmich.edu by following the process outlined in the video linked below.

NOTE: Access to self-service options requires your account security question and answer.

Option 2

Contact the OIT Help Desk by phone at (989) 774-3662 or by chat at helpdesk.cmich.edu for assistance.
