What's the preferred method for two factor authentication? (SMS, Voice, Duo Mobile Push)

Answer

Duo mobile is the preferred method for your two factor authentication. The application can run on a tablet, or a smart phone (Android or iOS). Here are some details as to why the application is preferred over SMS or voice:

• Less intrusive and the fastest method for confirming your identity
• The app will let you know where the login attempt is coming from, which lets you know if someone else is trying to access your account
  • Be sure to click "Deny" if a login attempt is not initiated by yourself
• The app is lightweight and doesn't require additional permissions to your phone/tablet
• Cost's the university less versus the other methods (SMS and Voice)
  • Each SMS/Voice incurs a cost for the university, whereas the Mobile App carries no cost.
