An SSO ID (Single Sign-On Identity) is a single digital identity that enables users to log in once and access multiple applications without repeatedly logging in. It streamlines authentication, bolstering security and enhancing user experience through minimized password fatigue. Organizations receive the advantage of centralized identity management, better compliance, and cost savings on IT support due to fewer password resets. But if an SSO ID is compromised, it may put many systems at risk for security breaches. To minimize risks, companies must insist on Multi-Factor Authentication (MFA), strict session management, and real-time security monitoring to identify unauthorized access.
