What is Two-Factor Authentication?

Two-factor authentication adds a second layer of security to your online accounts by requiring a second piece of information before you can log-in to a site. Verifying your identity using a second factor (a temporary code created for you and sent to/by another device) improves privacy and security.

Why do I need UL2FTCR?

Through Duo's two-factor authentication, UofL's Information Technology can provide better protection for your personal information and increase the security of campus data assets. The second factor of authentication is separate and independent from your UofL userID and password. The two-step confirmation process insures that you are the one accessing your account.

UL2FCTR / Duo is easy to use - simply follow the steps as prompted. For more information, check out these videos. If you have issues, contact our IT HelpDesk.

How it works

You will need your UofL userID and password to begin on a desktop or personal computer plus an additional device that only you have, such as a smartphone or tablet. UL2FCTR / Duo uses that second device to deliver the second factor. Specifically, it generates a second, temporary password and sends it to you, typically by text or via an application so that you can verify the access. Downloading the application or use of a device for this process is highly recommended but optional. UofL is not liable for costs associated with the use of a device including data, overages or roaming charges.

No smartphone? You can use any phone or ask your supervisor for a UofL approved hardware token (best for those needing frequent access). UL2FCTR / Duo lets you link multiple devices to your account so you can have several ways to receive that second factor or provide the needed confirmation code.
