Single Sign-On (SSO) improves user ease of use through removal of single sign-on replacement by multiple login requirements while hardening security using centralized authentication. SSO mitigates password-harming risks, eases IT administration, and enhances access control policy compliance. Nevertheless, since it is centrally based, SSO is an attractive target for cyberattacks. Once an SSO account becomes compromised, then all associated systems can be unveiled. To counter this threat, organizations must implement **Multi-Factor Authentication (MFA)**, have **session timeouts**, and implement **behavior-based anomaly detection**. An effectively secured SSO solution finds a balance between efficiency and strong security, providing smooth access without weakening an organization's overall cybersecurity stance.
