Azure Active Directory (Azure AD) is Microsoft's cloud-based identity and access management service. It serves as a comprehensive solution for managing user identities, ensuring secure access to resources, and providing authentication services for applications.
The new name for Azure Active Directory is Microsoft Entra ID. Microsoft rebranded Azure AD to Microsoft Entra ID to align it with the broader Microsoft Entra product family, which encompasses a range of identity and access management solutions. The core functionality remains the same, but the name change reflects Microsoft's evolving focus on comprehensive identity solutions across the cloud.
