How to Set Up 2FA with DUO Mobile

Make sure that you are off the campus network when setting up 2FA for the first time or the BYUI network will automatically log you in. 
These instructions are only for setting up 2FA using push notifications. If you do not have a smartphone, visit that article Setting Up 2-Factor Authentication Without the Duo Mobile App to find out how to sign up without an app. Be aware that while phone calls and text messages cost the school money, push notifications are free. If you have a smartphone, we ask that you use push notifications.

If you are a student at BYU-Idaho, you will be required to enroll in 2-factor authentication (2FA). For more about 2FA, watch our Introduction: Why 2FA? video.

If you receive a notification like this when you are not trying to log in to your account, it means that someone is trying to get into your account. Open the notification and tap the red X to deny the request, and make sure to change your BYU-Idaho password as soon as possible.

You're now set up with 2FA and logged in to your account. You'll only need to do this when logging in to your BYU-Idaho account from an off-campus network, and only every 30 days per device and browser.
