Hello @GA-5121,
Thank you for posting your query on Microsoft Q&A.
Based on your description, I understand that you need to identify which users have reset their MFA methods after being instructed to do so. You can easily obtain this information from the Azure Portal. Navigate to Microsoft Entra ID >> Security >> Authentication methods >> Registration and reset events.
From there, you can filter the data to generate the report you need and download it in .csv format for easy viewing.
For more details, refer to the following link: Registration and reset events
I hope this information is helpful. Please feel free to reach out if you have any further questions.
