Description

Designated users are prompted to use their multi-factor authentication (MFA) process when signing in.

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. Please see References for creating this.

Note: Starting July 2024, Microsoft began requiring MFA for all users, including break-glass accounts. By the end of October 2024, this requirement was enforced. Physical FIDO2 security keys or a certificate kept on secure removable storage can fulfill this MFA requirement. If opting for a physical device, that device should be kept in a secure, documented physical location.
