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.
