| Where | What you need | | --- | --- | | In Microsoft Entra ID | Admin permission in YOUR OWN Entra ID directory (`portal.azure.com`) to register an application — it's your own directory, not one belonging to your provider for this platform. | | In Power Platform admin center | Admin permission on the Dataverse environment (`admin.powerplatform.microsoft.com`) to add an application user and assign it a security role. | | In Platform | Admin role to connect, activate actions or disconnect. Editor and Viewer roles can only see the connection's status. | > **Note — Each tenant registers ITS OWN app — never a shared one** > > Unlike Excel/Microsoft 365 (Manual 26, a single multitenant app owned by your provider for this platform), Dynamics 365 requires **your own business** to register an app in ITS OWN Entra ID: you never depend on your provider handing you an application identifier — you look up and manage your own from start to finish.
