Duo: Managing Devices in Duo Mobile

What is Duo Mobile?

Auburn University uses Duo Security to prompt individuals for a secondary confirmation of their identity at log in using a physical device in their possession. This process is called multi-factor authentication, or MFA. The physical device may be a smartphone or tablet using an app, a text message to a phone, an automated voice call to landlines or cell phones, or a hardware token.

AU employees and students are strongly encouraged to register at least two alternative devices, such as a smartphone or cell phone number (as a landline) or a tablet.

Why Do I Need Duo Mobile?

Duo Mobile is a security requirement for AU employees and students. Duo Mobile uses multi-factor authentication to confirm your identity when accessing certain university resources.
