@mrjohn44141 Thank you for reaching out to us, As I understand you are looking for differences between these two CA templates Require multifactor authentication for admins accessing Microsoft admin portals (CA016) vs Require MFA for Azure management (CA006).
A new application group called Microsoft Admin Portals (Preview) in conditional access policy management wizard which protects five Microsoft admin portals:
- Microsoft 365 Admin Center
- Exchange admin center
- Azure portal
- Microsoft Entra admin center
- Security and Microsoft Purview compliance portal
The Microsoft Admin Portals app group applies to interactive sign-ins to the listed admin portals only. Sign-ins to the underlying resources or services like Microsoft Graph or Azure Resource Manager APIs are not covered by this template. Those resources are protected by the Require multi-factor authentication for Azure management template
