What is Azure Directory?

Azure Active Directory (Azure AD) is Microsoft's cloud-based identity and access management service. It is used to manage user identities and control access to applications and resources within an organization and in the cloud. Azure AD provides authentication, authorization, and directory services, enabling single sign-on (SSO) for users across various applications and services, including Microsoft 365, Azure resources, and thousands of other SaaS applications. It is commonly used for user management, device management, application access control, and identity protection.
