Overview

Duo two-factor authentication is an extra layer of account security. It requires you to confirm your identity using your Login credentials and a personal device when trying to access University systems.

See information about supported and unsupported smartphone platforms for Duo Mobile.

Restore or Reactivation

If you get a new phone with the same phone number, you must restore your Duo account to the new one before you can sign in. 

If you have a new phone with a different phone number, you need to contact the UTHSC Service Desk at 901.448.2222 or 1800.413.7830 to obtain a bypass code.

If you have an iPhone and restore your phone from an iCloud backup, restoring Duo mobile is easy. Just launch the Duo app and tap Continue. If you do not restore from an iCloud backup or have an Android phone, continue below.

1. Once you have your new phone, go to 2fa.utk.edu/restore.
2. Log in with your NetID and password, and additional verification information.
3. Select one of the Duo methods to log in. 
   1. Call Me: Call the cell phone number already registered.  Select 7 to approve.
   2. Enter a Passcode: Select ‘Text me new codes’ to receive an SMS message with new temporary codes to the phone number registered (only works if you have the old phone).
   3. Send Me a Push (only works if you have the old phone and are on a network).
