When authentication is decentralised across applications, access decisions and trust relationships often vary by owner. That inconsistency produces unmeasured authentication risk, inconsistent treatment of session federation and unclear accountability for access decisions.
Single Sign-On defines a documented, auditable control framework for centralised authentication and session federation. It records responsibilities, acceptance criteria and measurable controls, and sets the governance boundary—covering roles, responsibilities and trust relationships while excluding operational procedures, endpoint or device management, application authorisation design and procurement decisions.
