If you have previously set up Duo and need to re-set up the app on a new device or get an error that Duo is "Disabled", you may be prompted for an authentication code or QR code. If so, follow the "Adding a New Device" section of this article.
First-time Enrollment
If you are new to Chico State, the first time you sign into a Campus Service, you will be prompted to complete a self-enrollment for Duo.

Adding a New Device
Duo Prompt Screen
If you are already enrolled in Duo and trying to set up a new device, you will not receive the same self-enrollment pop-up for Duo. Instead, you will see the Duo prompt screen. You will need to click Other options then Manage devices:

NOTE: This method of adding a new device will require you to either have the old device or a Duo Token to authenticate. If you have no other way to add a device, put in a ticket here: https://support.csuchico.edu/TDClient/1984/Portal/Requests/ServiceDet?ID=24788
You will have to authenticate in order to get to the next screen. Choose to Send a Push to the old device or Enter a Passcode from the token generator. After authenticating in, you'll see a screen that says "You're Verified. Sending you to the devices page".
Choose Your Authentication Device
On the Devices page, you will be able to see all devices attached to your account. If this is the same phone number, but a new device, you can select the I have a new phone option. From here, you can scan a QR Code or get an activation link sent to your device. If this is a new device and a new phone number, you will choose the Add a device option and walk through the on-screen steps.

Congratulations! Your device is ready to approve Duo authentication requests. After clicking Back to login, you can test the Duo Push option to give it a try. All you need to do is tap Approve on the Duo login request received on your phone.
Configuring Device Options (optional)
You can use the Devices page to give your phone a more descriptive name, remove old devices, or you can click Add a device to start the enrollment process again and add a second phone or another authenticator.
