Report on MFA Prompts

Copper Contributor

I need to provide evidence to management on the number of MFA prompts users are receiving to determine suitability of our configuration. I know I can select an individual logon event where conditional access is classed as successful to determine what authentication method is used but is there a way to generate a report say on all MFA authentications passed by App Notification, Phone Call or SMS and ignore those passing due to existing token or hybrid joined device.

You can either export the Azure AD Sign-in logs and pivot the data or plug it into Sentinel or some other system. The new Insights dashboard could also help:

@VasilMichevI know the dashboard says it is in preview, but I'm seeing weird results, and I don't know if this is because of our configuration, or errors in the report.   I had always assumed our configuration was not supported for this report.  We're using MFA server (not Azure MFA server), but we see a small number of users appearing in the report and I can see no pattern behind this.

Not sure if MFA server is supported, sorry.

Thanks@VasilMichev the Usage & Insights includes the data I need but I have to generate reports per application. I also seem to be limited to 5200 results when downloading each applications sign-in report regardless of timescale selected. This is a pain for applications that have a large number of sign-ins.

Thanks @VasilMichev.  Kind of guessed that was the case.  Just bizarre that it reports some data  - I expected to see no data at all.
