Hi there!
Some of you may know about this already, but sharing some good news. One of our third party apps is using Microsoft Reporting Web Service, which uses basic authentication. Just saw Microsoft's announcement today, Jan. 26, that Microsoft Reporting Web Service will now use Modern Authentication sometime next month.
OAuth interface for Office 365 Reporting web service MC318316 · Published Jan 26, 2022
Message Summary
Currently, users accessing Reporting Web service use “Basic Authentication” and must provide their credentials. With this feature update, Microsoft will improve the security of your tenant by replacing “Basic Authentication” access in favor of the recommended OAuth user interface which is where we will continue to invest our development resources.
Key points
Timing: Rollout will begin in mid-February and is expected to be complete by late February.
Action: Users will need to provide their credentials in the OAuth user interface instead of utilizing the "Basic Authentication" interface.
How this will affect your organization:
Customers accessing the Reporting web service from browser will now see the OAuth dialog instead of "Basic Authentication". It will not be a significant change for users.MC318316 ·
Thank you, Microsoft team.
