Two Factor Authentication is also known as 2FA, two-step verification, or TFA. It is an extra layer of security added to accounts that requires not only a password and username but also an extra code that the user generates on a device they have – most often their smartphone.

The University’s 2FA provider is a company named Duo Security (Duo for short). After you enroll in 2FA and when you log in to an RCC system, you will enter your username (CNetID) and password as you do now. Then you will use your smartphone or another device that has duo installed to verify your identity.

The RCC is bringing its systems in-line with the wider University of Chicago policy. 2FA is a way to secure the online identity and personal information of all faculty, students, staff. It also adds another layer of protection for the University’s research, intellectual property, and institutional data.

If you have any questions or comment, you can get more information by visiting the RCC’s 2FA website, calling the RCC’s help desk at 773-795-2667, by emailing, or by visiting the walk-in lab in room 216 of the Regenstein Library.
