Two-factor authentication is simple and effective way of increasing the level of security when logging in to CAS. The combination of a classic password and another, independent element of authentication, e.g. a hardware key, significantly reduces the risk of unauthorized account access, even if your password becomes compromised. This safety measure protects user accounts as well as sensitive data accessible via CAS.
Furthermore, two-factor authentication is simple and accessible. Logging into an account remains quick while ensuring the system grants access to authorized personnel only. Due to higher demands on cybersecurity, this form of authentication is being required by an increasing number of systems and its implementation into CAS is an important step towards protection of the university environment.
It is desirable to activate two different types of two-factor authentication in case one of them becomes inaccessible. We recommend using the CU Key mobile app combined with a code sent by text message as a backup. If you require further assistance with two-factor authentication settings, please contact your local IT support.
