security. By enabling one login to grant access to multiple applications, SSO helps eliminate password fatigue, lowers IT support expenses, and decreases security threats such as phishing and credential theft. Organizations enjoy simplified identity management, enhanced compliance, and better efficiency in their operations. SSO is a single point of failure if not secured, though. To reduce risks, companies should implement Multi-Factor Authentication (MFA), use least privilege access principles, and utilize continuous monitoring to identify and respond to potential threats in real time.
