#What is the Difference between App Profile and Service Account Profile?

Auto discovery requires an authentication method, either using a service account profile or an app profile. The app profile authentication method is recommended in most cases, and auto discovery scan profiles use the app profile authentication method as the preferred option. By using the app profile authentication method, the app token will be used to back up or manage data, and the credentials of the Administrator account will not be stored by AvePoint Online Services.

However, the service account authentication is required by some services. For more information, refer to Will the App Profile Method Meet Your Data Management Requirements? If you configure a service account profile, the credentials of the account within the profile will be used to scan and manage Microsoft 365 objects. For details on configuring service account profiles, refer to Manage Service Account Profiles.
