Single Sign-On (SSO) is an identity access management (IAM) solution that allows users to log in once and gain access to multiple applications and systems without needing to authenticate separately for each one. By centralizing user authentication, SSO simplifies user experience, improves productivity, and greatly enhances security posture by reducing password fatigue and minimizing weak or reused credentials—one of the leading causes of data breaches.
From a security standpoint, SSO helps protect business data by enforcing strong authentication methods (often integrated with multi-factor authentication), reducing attack surfaces associated with multiple login points, and offering centralized access controls. SSO also improves IT oversight by enabling administrators to manage and revoke access rights from a single platform, ensuring that only authorized users have access to critical systems. Additionally, it supports regulatory compliance by maintaining detailed audit logs, access histories, and identity verification for user actions across all connected services.
