The proposed solution is incorrect. The Authentication methods section within the Microsoft Entra admin center is used to enable and target Windows Hello for Business (WHfB) for users and groups. However, it does not contain the granular policy settings for configuring PIN complexity, such as minimum length. These device-specific configurations are managed through a device management solution. For cloud-managed, Azure AD-joined devices, the correct method is to create and assign a device configuration profile in Microsoft Intune. Specifically, an Identity Protection profile allows an administrator to configure settings like Minimum PIN length, uppercase letters, lowercase letters, and special characters for the WHfB PIN.

A. Yes: This is incorrect because the Authentication methods policy in the Microsoft Entra admin center only enables the WHfB service; it does not manage the specific PIN requirements on the endpoint device.

1. Microsoft Learn | Microsoft Intune Documentation. "Identity protection profile settings for Windows Hello for Business in Microsoft Intune." This document details the settings available in an Intune Identity Protection profile, explicitly listing Minimum PIN length as a configurable option. It states, "Configure Windows Hello for Business on devices. This profile includes settings to configure PIN requirements..."

2. Microsoft Learn | Microsoft Entra Documentation. "Manage authentication methods for Microsoft Entra ID." This document outlines the capabilities of the Authentication methods policy blade. For Windows Hello for Business, the only available settings are Enable and Target, confirming that PIN complexity is not configured here. The page notes, "To configure Windows Hello for Business, see Windows Hello for Business Policy settings," which directs users to Intune and Group Policy documentation.

3. Microsoft Learn | Windows Security Documentation. "Windows Hello for Business Policy settings." This document provides a comprehensive overview of how to manage WHfB, stating, "Windows Hello for Business policy settings can be managed with Group Policy or a mobile device management (MDM) solution, like Microsoft Intune." It then details the specific policy settings, including those for PIN complexity, under the Intune and Group Policy sections.
