Specifying client ID and secret when creating an Azure ACS principal via AppRegNew.aspx will be removed [MC898388]
When using the AppRegNew.aspx page to create Azure ACS (Access Control Service) principals today, you can generate a new client ID (default flow) and secret, but you can also specify the client ID or secret yourselves. Going forward, the option to specify the client ID and secret yourself will be removed.
