How will Workspace 365 connect with Azure AD?

Workspace 365 will connect with Azure AD via a registered Azure AD application, which grants Workspace 365 permissions to use the desired API's.

Workspace 365 has the option to automatically create the Azure AD Application, so no user interaction is needed, only for the consent on the API permissions when the application is created. See this article for additional information.
