Q: I had Duo Mobile set up on my smartphone already, but it is no longer working. What can I do?


A: In order to fix this issue, please re-enroll your device. Ensure you have backup passcodes ready, and then delete the Duo application from your phone. Reinstall it as a new device – instructions are on our website https://calnetweb.berkeley.edu/calnet-2-step/2-step-devices.
