What is Duo Mobile?

Auburn University uses Duo Security for multi-factor authentication (MFA) to verify identity during login using a physical device. The physical device may be a smartphone or tablet using the Duo Mobile app, a text message to a cell phone, an automated voice call to a landline or cell phone, or a Duo hardware token. Users are encouraged to register at least two devices for backup. The Duo Mobile app is the recommended method for multi-factor authentication.
