Identity Management System (IDMS)

IDM/IGA Domain

Definition

An **Identity Management System (IDMS)** is an integrated set of technical and organizational components that create, maintain, and use digital identities for subjects such as users, devices, or services within a domain. It typically provides centralized functions for identity lifecycle management, including identity creation, update, deprovisioning, and integration with authentication and access control services. The term is generally used as an implementation‑level synonym of an identity management capability or infrastructure rather than a formally standardized product category.
