CUNY and CCNY have implemented Multi-Factor Authentication (MFA) for CUNY Login, CUNY Office 365, and CCNY applications. This added layer of security helps protect both your data and CUNY’s and CCNY’s data from potential cyberattacks.
While the experience will feel similar to the existing Citymail MFA, users must complete this setup specifically for their new email account: @stu-mail.ccny.cuny.edu. Having MFA for Citymail does not automatically cover this new mailbox.
