Change Phone Number (2FA/Duo)


This article describes what to do when your phone number changes and you no longer have access to the old number.

Until you update your phone number, you will not be able to sign in to your university account with Two-Factor Authentication (2FA) using Duo Mobile.

Note: NetID+ is the UA's branded term for 2FA so you may see this term used interchangeably with 2FA and Duo.
