App Registration vs Enterprise Application is one of the most common topics Microsoft Entra ID administrators and developers need to understand. While both features work together, they serve different purposes in identity management and application security.
Understanding Microsoft Entra ID application management helps organizations deploy secure applications, simplify administration, and strengthen identity governance. In this guide, we’ll explore key differences, use cases, and best practices to help you effectively manage applications, authentication, and access control within Microsoft Entra ID.
Microsoft Entra ID App Registration creates the identity of an application within a Microsoft Entra ID tenant. When an application is registered, Microsoft Entra ID assigns a unique Application (Client) ID that allows the application to authenticate users and securely access Microsoft services such as Microsoft Graph, Azure resources, and other protected APIs.
