Duo provides offline authentication options for times when you lack cell service or when using 2FA could cause you to incur extra cellphone charges, such as when you are traveling internationally. NOTE: In order to take advantage of the options below, be sure to register your device s for use with your 2FA account including, if applicable, downloading and installing the Duo Mobile App on your smartphone before you begin your travel. You can request single-use passcodes directly from the Duo Mobile app, even when your mobile device is in airplane mode or lacks cell service. If you do not have the Duo Mobile App installed on a mobile device, you can request a batch of passcodes to be sent via text message to your cellphone before you depart for your travel. You will need to request the passcodes before you leave, or while in an area with cell service, as you will need a cell connection to receive the text message on your phone.
Activating Offline Access with a Security Key
After entering your Microsoft Windows username and password, an authentication request will automatically be pushed to the Duo Mobile app on your phone. If auto-push is disabled or if you click the Cancel button on the Duo Prompt, you can select a different device from the drop-down at the top if you've enrolled more than one or select any available factor to verify your identity to Duo:. If your organization allows you to use this feature, you'll see the offline activation prompt after successful Duo two-factor authentication when you log in to, unlock the workstation, or approve a user elevation request while the system is online and able to contact Duo's service. Check with your organization's Duo administrators or Help Desk to verify availability of Offline Access on your workstation. If you're not sure whether your security will work, ask your organization's Duo administrator or your IT Help Desk.
Duo Mobile App (Smartphones and Tablets)
Duo Security is a multi-factor authentication tool used by the University of Vermont to protect sensitive information. Upon logging into a Duo-protected site, you will be required to perform an additional authentication step via Push notification to a smart phone or tablet, SMS text, or phone call. To use Duo you must enroll a device to act as your second authentication factor. Please use the guides below to enroll the device s that best suits your needs. Enterprise Technology Services recommends enrolling at least two devices. There are five physical devices that you can use to provide the second factor of two-step authentication.
Duo Security is now a part of Cisco. About Cisco. This is critical to support users whose job requires them to be temporarily offline, but who still need to perform 2FA to log in to their Windows computer. See our previous blog posts on the subject here and here. We also hosted a heavily-attended customer webinar, recorded here , where we addressed many common customer questions. This has the advantage of being very familiar for users who already use the OTP option in the Duo Mobile app on a regular basis.
