Duo Two-Factor Authentication

OU Health IT is adding an extra security measure to protect your private information. All OU Health employees will be required to use Duo when logging into password-protected work accounts outside of the hospital network

OU Health DUO Enrollment Instructions

What is my log-in for

Duo utilizes your OU Health login (same as your email login).  If you are unsure what your OU Health login is, use the OU Health Password Portal to manage your account. 

What is Duo Mobile?

Duo Mobile is a mobile application (app) that you install on your smartphone or tablet to generate passcodes for login or receive push notifications for easy, one-tap authentication on your mobile device. It works with Duo Security’s two-factor authentication (2FA) service to make your logins more secure.

What is the recommended two-factor authentication method?

If you have a smartphone or tablet, we recommend Duo Push, as it is quick, easy-to-use, and secure. See an introduction to Duo Security and a demonstration of Duo Push in this short video:

How much data does a Duo Push request use?

Duo Push authentication requests require a minimal amount of data -- less than 2KB per authentication. For example, you would only consume 1 megabyte (MB) of data if you were to authenticate 500 times in a given month.

Why have I stopped receiving push notifications from Duo Mobile?

There are several reasons this could be happening. Please try the following to troubleshoot:

  1. Make sure your enrolled device has a cellular network or WiFi connection.
  2. Have the Duo Mobile app open when you authenticate.
  3. Try these additional push troubleshooting steps:
  4. If the above solutions don’t work, try using another authentication method, such as passcodes provided in the Duo Mobile app.

How can I manage the devices I use for Duo?

If you can go to, log in with your OU Health credentials, and click the “My Settings & Devices” link at the Duo Prompt and are currently able to authenticate with a device, you may:

  • Add additional devices
  • Designate your “default” device that receives authentication requests in addition to your preferred authentication method
  • Deactivate Duo Mobile if you got a new phone but kept your number
  • Change the name of your device (ex. “Personal Cell” or “Work Phone”)
  • Remove a device

What should I do if I lost my phone?

Please contact the OU Health Service Desk immediately.



Can Duo see my password?

No. Your password is only verified by your organization and never sent to Duo. Duo provides only the second factor, using your enrolled device to verify it’s actually you who is logging in.





Does using Duo give up control of my smartphone?

No. The Duo Mobile app has no access to change settings or remotely wipe your phone. The visibility Duo Mobile requires is to verify the security of your device, such as OS version, device encryption status, screen lock, etc. We use this to help recommend security improvements to your device. You always are in control of whether or not you take action on these recommendations.

How can I reactivate Duo Mobile on my new phone?

If you get a new phone you'll need to re-activate Duo Mobile.




  • If you have your old device you may enroll your new device yourself using the device management portal at Once you have used your OU Health credentials to login, click the “Add a new device” link at the Duo Prompt. You will be asked to authenticate with a device, then you may add your new device.
  • If you no longer have a connected device to authenticate with Duo, you will need to contact the OU Health Service Desk or submit an online incident through the IT Service Portal.
