Description​

Microsoft Azure applies a default global banned password list to all user and admin accounts that are created and managed directly in Microsoft Entra ID. The Microsoft Entra password policy does not apply to user accounts that are synchronized from an on-premises Active Directory environment, unless Microsoft Entra ID Connect is used and EnforceCloudPasswordPolicyForPasswordSyncedUsers is enabled. Review the Default Value section for more detail on the password policy. For increased password security, a custom banned password list is recommended

Rationale​

Enabling this gives your organization further customization on what secure passwords are allowed. Setting a bad password list enables your organization to fine-tune its password policy further, depending on your needs. Removing easy-to-guess passwords increases the security of access to your Azure resources.

Impact​

Increasing needed password complexity might increase overhead on administration of user accounts. Licensing requirement for Global Banned Password List and Custom Banned Password list requires Microsoft Entra ID P1 or P2. On-premises Active Directory Domain Services users that are not synchronized to Microsoft Entra ID also benefit from Microsoft Entra ID Password Protection based on existing licensing for synchronized users.
