When you get a new smartphone with the same phone number, you will need to reactivate the device from the Duo Control Panel in order to use it for 2-Step.
Go to mycalnet.berkeley.edu and click Login in the upper right corner.
Log in with your CalNet credentials, and if prompted, do a 2-Step. If you need help doing a 2-Step, email calnet2-stephelp@berkeley.edu.
When you are logged in:
- Select Manage 2-Step.
- At the Device Control Panel, select a device to perform another 2-Step to access the panel. You'll be taken to My Settings and Devices.
- From there, click on Device Options next to the device on which you need to reactivate Duo.
- Click on Reactivate Duo Mobile to display a QR code.
- Open Duo Mobile on your phone, click the Plus symbol which activates the camera feature and then scan the QR code.
Note: If you have set up a secondary device, you may use that to authenticate. If you don’t have backup passcodes or a secondary device, please contact calnet2-stephelp@berkeley.edu to get help.
