Applications must be registered in a directory

Effective date: June 2024 Endpoints impacted: v2.0 and v1.0 Protocol impacted: All flows Change Previously, when registering an application using the Microsoft Entra app registrations experience, if the user was signed in with their personal Microsoft account (MSA), they could choose to only associate the application with their personal account. That means the application wouldn't be associated with or contained in any directory (also referred to as 'tenant' or 'organization'). However, starting June 2024, all applications must be registered in a directory. This could be an existing directory, or a new one that the personal Microsoft account user creates to house their Microsoft Entra applications and other Microsoft resources. Users can easily create a new directory to use for this purpose by joining the Microsoft 365 Developer Program or signing up for Azure. Registering an application in a directory, instead of only associating it with a personal account, has various benefits. These include: Applications registered in a directory have more features available to them, such as the ability to add more than one owner to the app, and the ability to publisher verify the app. The application is located in the same place as other Microsoft resources the developer uses, such as Azure resources. The application receives improved resiliency benefits. This won't affect any existing applications, including existing applications that are only associated with a personal account. Only the ability to register new applications will be affected.
