Gather data from MFA Server

For MFA Server version 8.0 or higher the following process allows administrators to export all data for users:

  • Log in to your MFA Server, navigate to the Users tab, select the user in question, and click the Edit button. Take screenshots (Alt-PrtScn) of each tab to provide the user their current MFA settings.
  • From the command line of the MFA Server, run the following command changing the path according to your installation C:\Program Files\Multi-Factor Authentication Server\MultiFactorAuthGdpr.exe export <username> to produce a JSON formatted file.
  • Administrators can also use the Web Service SDK GetUserGdpr operation as an option to export all MFA cloud service information collected for a given user or incorporate into a larger reporting solution.
  • Search C:\Program Files\Multi-Factor Authentication Server\Logs\MultiFactorAuthSvc.log and any backups for "<username>" (include the quotes in the search) to find all instances of the user record being added or changed.
    • These records can be limited (but not eliminated) by unchecking "Log user changes" in the MFA Server UX, Logging section, Log Files tab.
    • If syslog is configured, and "Log user changes" is checked in the MFA Server UX, Logging section, Syslog tab, then the log entries can be gathered from syslog instead.
  • Other occurrences of the username in MultiFactorAuthSvc.log and other MFA Server log files pertaining to authentication attempts are considered operational and duplicative to the information provided using MultiFactorAuthGdpr.exe export or Web Service SDK GetUserGdpr.

Delete data from MFA Server

From the command line of the MFA Server, run the following command changing the path according to your installation C:\Program Files\Multi-Factor Authentication Server\MultiFactorAuthGdpr.exe delete <username> to delete all MFA cloud service information collected for this user.

  • Data included in the export is deleted in real time, but it may take up to 30 days for operational or duplicative data to be fully removed.
  • Administrators can also use the Web Service SDK DeleteUserGdpr operation as an option to delete all MFA cloud service information collected for a given user or incorporate into a larger reporting solution.

Gather data from NPS Extension

Use the Microsoft Privacy portal to make a request for Export.

  • MFA information is included in the export, which may take hours or days to complete.
  • Occurrences of the username in the AzureMfa/AuthN/AuthNOptCh, AzureMfa/AuthZ/AuthZAdminCh, and AzureMfa/AuthZ/AuthZOptCh event logs are considered operational and duplicative to the information provided in the export.

Delete data from NPS Extension

Use the Microsoft Privacy portal to make a request for Account Close to delete all MFA cloud service information collected for this user.

  • It may take up to 30 days for data to be fully removed.

Gather data from Windows Server 2016 Microsoft Entra multifactor authentication AD FS Adapter

Use the Microsoft Privacy portal to make a request for Export.

  • MFA information is included in the export, which may take hours or days to complete.
  • Occurrences of the username in the AD FS Tracing/Debug event logs (if enabled) are considered operational and duplicative to the information provided in the export.

Delete data from Windows Server 2016 Microsoft Entra multifactor authentication AD FS Adapter

Use the Microsoft Privacy portal to make a request for Account Close to delete all MFA cloud service information collected for this user.

  • It may take up to 30 days for data to be fully removed.

Gather data for Microsoft Entra multifactor authentication

Use the Microsoft Privacy portal to make a request for Export.

  • MFA information is included in the export, which may take hours or days to complete.

Delete data for Microsoft Entra multifactor authentication

Use the Microsoft Privacy portal to make a request for Account Close to delete all MFA cloud service information collected for this user.

  • It may take up to 30 days for data to be fully removed.

Delete data for self-service password reset

Users can add answers to security questions as part of SSPR. Security questions and answers are hashed to prevent unauthorized access. Only the hashed data is saved, so the security questions and answers can't be exported. Users can go to My sign-ins to edit or delete them. The only other information saved for SSPR is the user email address.

Those assigned the Privileged Authentication Administrator role can remove data collected for any user. On the Users page in Microsoft Entra ID, click Authentication methods and select a user to remove their phone or email address.
