Qué comprueba
Users without any registered MFA methods cannot satisfy MFA challenges and represent critical security gaps. These accounts are fully exposed to credential-based attacks including password spraying, phishing, and brute-force attacks. Immediate remediation is required to ensure all active accounts have at least one MFA method enrolled.
Valor recomendado
Zero active users without at least one MFA method registered
Remediación
Query user registration details via Entra ID > Protection > Authentication methods > User registration details to identify users with no methods. Enforce MFA registration through a Conditional Access policy targeting unregistered users. Use Temporary Access Pass to assist users who need to bootstrap their MFA registration.
