Two-factor authentication (2FA) adds an extra layer of protection to certain University pages and applications that contain sensitive information. While the two-factor authentication process can be completed through phone calls, text messages, and hardware tokens, using the Duo Mobile app is recommended. For more information on two-factor authentication, visit the 2FA for FSU page.

How do I remove a two-factor authentication (2FA) device?
