What is the difference between SSO and IAM?

SSO (Single Sign-On) is one feature within IAM — allowing users to authenticate once and access multiple applications. IAM is the broader discipline covering identity lifecycle management (provisioning/deprovisioning), role-based access control, MFA, privileged access, and audit logging. Most IAM platforms include SSO as a core feature alongside these broader capabilities.

What is Identity & Access Management?

Identity and Access Management (IAM) software controls who can access what resources. SSO simplifies login across applications, MFA adds verification layers, and PAM (Privileged Access Management) secures high-risk administrator credentials. Together they form the foundation of a Zero Trust security posture.
