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
- When prompted to complete the 2-step select “Other options" and then "Manage devices"
- At this point, you will have to complete a 2-step in order to manage your devices. You can use an existing device, a security key, or a bypass code provided by the help desk
- Under your old device, select "I have a new phone"
- Follow the steps provided by Duo in order to connect your Duo account to your new device.
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.
