Quick Answer
The answer is that you must configure a PIN complexity policy, specifically a minimum PIN length of at least 4 digits, to enable Windows Hello for Business in Intune. This setting is mandatory because Windows Hello for Business relies on a PIN as a gesture tied to a device’s trusted platform module, and Intune’s identity protection policy will not activate the feature without an explicit baseline for PIN security. On the Microsoft 365 Endpoint Administrator MD-102 exam, this tests your understanding of the required settings for Windows Hello for Business in Intune, often appearing as a multi-select question where candidates mistakenly choose optional settings like biometrics or certificate enrollment. A common trap is assuming that enabling Windows Hello alone suffices, but Intune enforces the PIN complexity policy as a non-negotiable prerequisite. Remember the mnemonic “PIN First” — without a defined minimum PIN length, Hello won’t say hello.
This MD-102 practice question tests your understanding of prepare infrastructure for devices. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are configuring Windows Hello for Business in Microsoft Intune. Which THREE settings are required to enable Windows Hello for Business on Windows 10 devices?
Configure a certificate enrollment policy for smart cards.
Why wrong: Not required for Windows Hello.
Set minimum PIN length to at least 4 digits.
A minimum PIN length is required.
Enable biometric authentication.
Why wrong: Biometrics are optional.
Enable Windows Hello for Business in the identity protection policy.
This is the main switch to enable the feature.
Configure a PIN complexity policy.
PIN policy is required for Windows Hello.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Set minimum PIN length to at least 4 digits.
Option B is correct because Windows Hello for Business requires a minimum PIN length of at least 4 digits when configured via Intune's identity protection policy. This setting is mandatory to enforce a baseline level of security for the PIN-based authentication method, and Intune will not enable Windows Hello for Business without a defined minimum PIN length.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often assume biometric authentication is required for Windows Hello for Business, but Microsoft explicitly allows PIN-only deployments, and the mandatory settings are enabling the feature and configuring PIN complexity (including minimum length).
Detailed technical explanation
Windows Hello for Business leverages asymmetric key pairs (or certificates) stored in the TPM (Trusted Platform Module) for authentication, with the PIN acting as a user gesture to unlock the private key. The minimum PIN length setting is enforced via the Policy CSP (./Device/Vendor/MSFT/PassportForWork/PINComplexity/MinimumPINLength) and must be configured before the feature can be provisioned. In hybrid deployments, this policy is synchronized through Azure AD and Intune, and failing to set a minimum PIN length will result in a provisioning failure.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
