Beginning January 4, 2022, users will no longer be able to use the “call me” or SMS passcode options in Duo Security as these factors are susceptible to vulnerability and fraud.
How else can I use Duo?
The easiest and most secure option for two-factor authentication is to install the Duo Mobile app on your mobile device. Duo Push sends a notification to your phone using less data than a single email message, and with a simple click, you can authenticate. If you haven’t already, visit smu.edu/duo to download the app and enroll your device.
I don’t want to install the Duo Mobile app on my phone. What do I do?
Another option is to use a hardware token which is often easily carried on a key ring. These tokens either plug into the USB port on a computer or display a code for you to enter into the Duo login screen. Faculty and staff can inquire about a hardware token by emailing the IT Help Desk at firstname.lastname@example.org.
What if I forget my phone at home? How will I be able to log in?
Should you don’t have access to your mobile device, call 214-768-4357 from another phone, and someone from the IT Help Desk will assist you once they have verified your identity.
