As we embark into 2023, we are continuing our journey to make Power Pages platform more secure, robust and reliable. As part of this journey, we are introducing a change in how a Power Pages website connects to Dataverse by leveraging Dataverse Application User concept.
As described in Power Pages documentation, every Power pages website connects to underlying dataverse instance using an Azure Active directory application which is created when a new website is created. This Azure Active directory application is mapped to a special “SYSTEM” user in dataverse and all the connection by website is made in context of SYSTEM user.
