MFA with Duo Frequently Asked Questions
We recommend registering multiple devices in Duo because this will provide a backup method of authenticating with Duo when your primary method is not available.
If you have multiple devices registered in Duo, only the device that you select as your "Default Device" will receive the Duo prompt. You will not receive Duo prompts from every device each time you authenticate.
To enroll a secondary device:
- Go to the Duo Identity Management page
- Select the Duo Multifactor Authentication module
- Authenticate with Duo
- Select +Add another device
- Add a secondary device
- Ensure that your preferred primary Duo device is set as your "Default Device."

If you have a secondary device enrolled with Duo
If you have registered a second device in Duo, you can select your backup method from the list of Duo options, and authenticate that way.
If you have not set up a secondary device
If you are being prompted to authenticate with Duo and only have a smartphone enrolled in Duo, you will need to request support.
We can help you log in if you can be verified another way. We may also be able to set up a second device for you (hard token or another smart device) so you can avoid this problem in the future.
Contact the IT Services Desk at (805) 893-5000 (x5000) or submit a ticket at ithelp.ucsb.edu.
The mobile “Send me a Push” function uses the phone's internet or cell connection, whichever is available. If you are on campus, you can connect to Eduroam for WiFi, so Duo will not use your cell connection.
If you are not on Wifi, Duo pushes consume a tiny amount of data. Each push consumes less than 2KB of data, which means it would take 500 authentications a month to reach 1MB of consumption. To learn more, read How Much Data Does a Duo Push Request Use? on the Duo website.
The "Enter a Passcode" function does not consume any data. If data consumption is a concern, we recommend using the passcode feature.
If you accidentally deny the Duo push on your smartphone, you will be asked why you denied the request.
If you accidentally denied the request, select “It was a mistake.”
If you accidentally pressed deny, and then also pressed "It seems fraudulent," contact the IT Services Desk at (805) 893-5000 (x5000).
Contact the IT Services Service Desk at (805) 893-5000 (x5000) or submit a ticket via the IT Services Catalog immediately under End User Services, then, Accounts & Access if your hard token is lost or stolen so they can lock the hard token until you get a new one. To enroll the new hard token, contact the IT Services Desk.

The Duo mobile app does collect information from your device when you attempt to authenticate using that device. The data that is collected is not user identifying, and is not used to track what you are doing.
Duo collects two types of information from you.
The first type is used to provide information about your authentication attempts, such as your hardware model, operating system, unique user and device identifiers, connection information and IP address. The transmission of this information cannot be disabled.
The second type of information that the Duo Mobile app collects is analytical data such as how you use the Duo Mobile app, the screens you use within Duo Mobile, and the actions you perform. You can disable the collection of your Duo usage data. To do this, open the Duo Mobile app, go to Settings and turn off Send usage data.
