This article explains how to reactivate your Duo Mobile account if your registered device changes. This is usually needed when you get a new phone or phone number.

Reactivation is required anytime a device enrolled in Duo becomes disconnected from your account. If you’re setting up 2FA for the first time, see the main 2FA article.

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