If you don't have access to your Duo Two-Step enrolled device, and only have one device registered, you have three options:

  • use a (previously generated) backup code that you saved
  • enroll a new phone as an alternate and then select it at login 
  • retrieve your device 

Find instructions on how to generate backup codes or enroll another device (like an office phone). You can't enroll a shared phone if someone else already enrolled it in Duo.

After enrolling another device, choose the new device from the device drop-down when you're prompted for two-step login verification. 

For faculty and staff, it is recommended to enroll your office phone number as a backup to use in the event that you forget your cell phone.
