Single Sign-On (SSO) revolutionizes the way organizations handle authentication by offering a seamless user experience and improved security. With SSO, users only need to remember one set of credentials to access a range of applications, which reduces password fatigue and enhances productivity. Additionally, SSO streamlines user management for IT teams, enabling easier onboarding and offboarding processes. However, SSO introduces risks like a single point of failure: if an attacker compromises the SSO account, they gain access to all linked systems. To mitigate this risk, integrating Multi-Factor Authentication (MFA) and strong access control policies is essential for ensuring robust security while maintaining convenience.
