FAQ: HSC Duo Two-Factor Authentication

Why Do I Need Duo Two-factor Authentication?

Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account. Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. If you receive an authentication request to your Duo Smartphone or tablet app and are not attempting to login to a OUHSC system protected by two-factor authentication, Deny the login request and contact the IT Service Desk immediately; your account credentials have been compromised.


How does two-factor authentication work?

Once you've enrolled in OUHSC’s two-factor authentication system, you will login to protected applications as usual with your HSC UserID and password. If you are off-campus (or on campus for some services), you will be prompted to send a request for authentication to the smartphone or tablet you registered at duo.ouhsc.edu. Approve the login from the smartphone or tablet, and the webpage on your computer will automatically refresh to the location you are attempting to reach.


What is considered off-campus?

Off-campus would include your home internet connection, public internet locations, connectivity via the HSC connect.ouhsc.edu VPN service, or even cellular data connectivity regardless of physical location. Only dedicated HSC wired and wireless networks are considered to be on-campus for two-factor authentication.


What HSC applications are protected by two-factor authentication?

  • Employee self-service access from off-campus
  • Student self-service access from off-campus
  • VPN (connect.ouhsc.edu)
  • Direct deposit from both on and off campus
  • Password Management Tool (effective September 10, 2018)
  • Webmail (webmail.ouhsc.edu only)


What do I need to use Duo?

You can use a smartphone or tablet. If it is an Android, it must be on version 6.0 or higher. If it is an Apple device, it must be on iOS 10.0 or higher. 


What happens if I loose my device or get a new device?

If the device linked with Duo is lost or stolen, or if you get a new device which replaces your old device, you'll need to contact the IT Service Desk for assistance.
