Microsoft Entra IDOverview
Designated users will be prompted to use their multi-factor authentication (MFA) process upon login.
Rationale
Enabling multi-factor authentication is a recommended setting to limit the use of Administrative accounts to authenticated personnel.
Impact
There is an increased cost, as Conditional Access policies require Microsoft Entra ID P1. Similarly, MFA may require additional overhead to maintain. There is also a potential scenario in which the multi-factor authentication method can be lost, and administrative users are no longer able to log in. For this scenario, there should be an emergency access account. See Plan a Conditional Access deployment before deploying this.
Default Value
By default, MFA is not enabled for any administrative accounts.

After testing the policy in report-only mode, update the Enable policy setting from Report-only to On.
Service-wide remediation
Recommended when many resources are affected: fix the platform baseline first so new resources inherit the secure setting, then remediate the existing flagged resources in batches.
Microsoft Entra ID
Use tenant-wide Conditional Access, role settings, authentication policies, and identity governance baselines so the control is enforced centrally.
Operational rollout
- Fix the baseline first at the account, subscription, project, cluster, or tenant scope that owns this control.
- Remediate the currently affected resources in batches, starting with internet-exposed and production assets.
- Re-scan and track approved exceptions with an owner and expiry date.
Query logic
These are the stored checks tied to this control.
