Can you see the applicationID? Here's what I see in my tenant:

Common Data Service '00000007-0000-0000-c000-000000000000': 'Dynamics CRM Online'

Those are all using modern auth though.

VasilMichev - Thanks 🙂 - it's the same AppId - if modern is used in common data service - why is it then listed under 'insights and reporting' in Cond. access sign in details and in the Identity Protection as Legacy Auth. sign in?
I've read this: https://techcommunity.microsoft.com/t5/azure-active-directory-identity/new-tools-to-block-legacy-authentication-in-your-organization/ba-p/1225302#

And the common data service is also listed in the workbook 'Sign-in using Legacy Authentification'

I made (several) Cond. Access - all running in reporting mode to get an overview of the impact, what is using leg. auth. etc. - one CA is to Block Legacy Auth. and followed this: https://docs.microsoft.com/en-us/azure/active-directory/conditional-access/block-legacy-authentication
