Two-Step Login blocks criminals from using stolen Cornell passwords by requiring something they don’t have. Something in your possession.
When it’s time to sign in using Two-Step Login, you confirm your identity by:
Responding to a push to the Duo app
- Entering a code from a hardware token
- Tapping the button on a USB device (security key)
Choose Your Device
- Required: Choose the device you want to use most often with Two-Step Login.
- Strongly Recommended: Choose a backup device in case your first choice is unavailable (left at home, out of charge, lost, or stolen).
