Updating Multi-factor Authentication to use Duo Mobile on the new model of an Android or iPhone
If you kept the same phone number, replaced your phone with a new phone of the same type (e.g., replaced an Android with another Android, or replaced your old iPhone with a newer model) and use Duo Mobile for notifications, you will need to reactivate Duo Mobile to use your new phone.
- Make sure you have your phone available and that you have adequate cell phone coverage in your location.
- On your phone, download the Duo Mobile app from the Google Play or iPhone App Store. Make sure you have the app installed before proceeding.
- On your computer, go to northwestern.edu/mfa-register and log in with your NetID and NetID password.
- Click reactivate and follow the subsequent steps. As you complete these steps, you will receive a confirmation notification on the phone you've just reactivated.
