The proposed solution is incorrect. Windows Hello for Business policies, such as PIN length and complexity, are not configured within the User or Device settings of the Microsoft Entra admin center. These settings are managed through device management solutions like Microsoft Intune. To change the PIN requirement from four to six digits for Entra ID joined devices, an administrator must create a device configuration profile in the Microsoft Endpoint Manager admin center. Specifically, an Identity Protection or Account Protection policy would be created, where the "Minimum PIN length" setting for Windows Hello for Business can be configured to 6 and then assigned to the appropriate devices or users.

A (Yes): This is incorrect because the specified locations (User settings and Device settings in Microsoft Entra admin center) do not contain the necessary controls to manage Windows Hello for Business PIN policies.

1. Microsoft Learn | Microsoft Intune Documentation. "Identity Protection profile settings for Windows devices in Microsoft Intune." This document explicitly lists the configurable settings for Windows Hello for Business within an Intune policy

including "Minimum PIN length

" "Maximum PIN length

" and complexity requirements. It confirms that Intune is the correct management tool.

Reference Section: Windows Hello for Business > Configure Windows Hello for Business settings > PIN minimum length.

2. Microsoft Learn | Microsoft Entra Documentation. "Configure device settings." This official documentation details the options available on the "Device settings" page in Microsoft Entra. The settings listed include options for device join

local administrators

and MFA for registration

but there are no settings related to Windows Hello for Business PIN configuration.

Reference Section: The entire article describes the available settings

none of which include PIN complexity.

3. Microsoft Learn | Windows Security Documentation. "Manage Windows Hello for Business in your organization." This document outlines the different methods for managing WHfB policies. For cloud and hybrid deployments

it specifies that policies are configured using either Group Policy or a Mobile Device Management (MDM) solution like Microsoft Intune.
