Entra Id: Turn Off MFA for SService Account Power Platform

Key insights

• Entra ID: Entra ID (Azure AD) manages identities for Power Platform and enterprise apps, so avoid turning off MFA globally.
  Disabling MFA weakens account security and increases risk for lateral attacks and data exposure.
• Service account: Service accounts are non-interactive accounts used by automation and connectors; they should not use regular user MFA workflows.
  Treat them as privileged identities and limit their scope and access.
• Power Platform: Power Platform connectors often need stable credentials for flows and integrations, but using a human user account with MFA disabled is risky.
  Prefer non-user authentication methods so flows run reliably without removing security controls.
• Service principal: Create an app registration (service principal) and grant only the required API permissions or roles.
  Use certificate-based authentication or short-lived secrets, assign least privilege, and document the app’s purpose and owners.
• Managed identity: When running in Azure, use system-assigned or user-assigned managed identities to avoid stored credentials altogether.
  Managed identities simplify rotation and improve security compared with disabling MFA on a user account.
• Conditional Access: If you must exempt an account from MFA, create a narrow Conditional Access policy that targets only that account or group, restricts sign-in locations and devices, and uses time-limited exceptions.
  Log activity, perform access reviews, rotate credentials regularly, and require approval before making changes.
