Two-Factor Authentication

At the University of Cincinnati, we're committed to your digital security, choosing Duo for Multi-Factor Authentication to safeguard both your personal and university data.

Strengthen Your Security with Duo

Duo's approach is straightforward yet powerful: it combines something you know (your password) with something you have (a mobile device). This method significantly bolsters your defenses against unauthorized access. If someone manages to crack your password, they still face the hurdle of the second verification step, which is uniquely yours. It's a personalized shield, adding a robust layer of security to your individual UC experience.

The Duo Mobile App

Choosing the Duo Mobile app is a step towards personal empowerment in your digital security journey. Features like Duo Push and one-time passcodes transcend the traditional methods of text and phone call verifications are; they are designed for your convenience and security. For detailed guidance on enrolling your device with the Duo Mobile app, please visit the Digital Technology Solutions page.

Duo Universal Prompt

The University of Cincinnati's rollout of the new Duo universal prompt for two-factor authentication, starting December 14th, enhances the digital security experience with a modern and streamlined design. This update simplifies the login process by defaulting to your last used authentication method and introducing the "Yes, trust browser" option for easier reauthentication​​​​.

  • Public Computer Caution: Avoid selecting 'Trust this browser' on public computers or devices you don't own. This ensures your account remains secure even if the device falls into the wrong hands.
  • Stay Alert for Suspicious Activity: Report any unexpected Duo authentication prompts immediately. If you receive a prompt without initiating it yourself, it could indicate an unauthorized attempt to access your account.
  • Regularly Review Your Devices: Periodically check the devices registered in your Duo account. Remove any old or unused devices to minimize security risks.
  • Keep Your Information Private: Never share your Duo authentication methods or passcodes with others. Your security credentials are personal and should remain confidential.


Almost none. 500 pushes to your device will use about 1 MB of data in total, which is roughly equivalent to loading one webpage on your smartphone.

No, the app does not have access to or visibility into your phone beyond what any other app would. Duo Mobile cannot read your emails, track your location, see your browser history, and it requires your permission to send notifications. It also cannot remotely wipe your phone.

The app only needs to access your camera when scanning a QR code during the activation process. This is a one-time requirement for setting up the app on your device.

You can still authenticate without an internet connection or cellular signal. Simply tap the icon in the Duo Mobile app to generate an authentication passcode. These passcodes can be generated offline.
