Power Automate Flow for MFA Method Registration Alerts

Power Automate Flow for MFA Method Registration Alerts is a custom-built automation that enhances your organization’s security posture by monitoring changes to user authentication methods.

This flow leverages Microsoft Graph API to detect when a user registers a new Multi-Factor Authentication (MFA) method and sends real-time email alerts to designated administrators or security teams.

Key Features

Graph API Integration: Uses Microsoft Graph API to fetch real-time data on user authentication method changes.

Email Notifications: Sends detailed alerts via Outlook every 30 minutes.

Lightweight & Scalable: Easily deployable across Microsoft 365 environments with minimal overhead.
