Explanation
Single Sign-On (SSO) is an identity management feature that allows users to log in to Salesforce using their university login credentials. SSO simplifies the login process and reduces the need for multiple passwords.
Named Credentials, Two-factor Authentication, and Social Sign-On are not identity management features that allow users to use their university login when accessing Salesforce. References:
