Softwarium added support for the OAuth 2.0 access tokens when working with SharePoint Online. This opened the door for allowing the client to use the Microsoft Graph API. Using OAuth Authentication also allowed employees to get access via web browser connection which does all of the dirty work, such as generating the access token, refresh token, the authorization code and other information necessary to log in.
This included adding support for the Authentication App registration when the connection to the target is made via browser since this generates the OAuth access token. This means that even if an employee performs the browser authentication and the target login does not find the application, we do this automatically. All they have to do is click a checkbox confirming that it is their Client ID. This also applies to GCC HIgh tenants, which are used by government organizations and contain sensitive information.
