How to Plan a Passwordless Rollout With Windows Hello and Authenticator

Retrospective: this article looks back at events from September 2018, written in 2026 with the benefit of hindsight.

Passwordless sign-in removes the most attacked credential and improves user experience. Here is a practical rollout plan using Windows Hello for Business, passkeys in Microsoft Authenticator and FIDO2 security keys.

Step 1: Choose methods by persona

Office workers on managed Windows PCs: Windows Hello for Business.
Mobile and frontline workers: passkeys in Microsoft Authenticator.
Administrators and high-risk users: FIDO2 security keys or device-bound passkeys.
Shared devices: FIDO2 security keys.

Step 2: Prepare prerequisites

Enable the methods in the Entra authentication methods policy.
Configure Windows Hello for Business through Intune (cloud Kerberos trust is the simplest model for hybrid environments).
Enable Temporary Access Pass for bootstrapping new users and recovery.
Check app compatibility — legacy apps that only support passwords need a plan.

Step 3: Pilot

Start with IT and a willing business team. Measure registration success, sign-in issues and help desk calls.

Step 4: Roll out by group

Use registration campaigns and communications. Provide short guides for each method.

Step 5: Enforce

Use Conditional Access authentication strengths to require passwordless or phishing-resistant methods for groups that have completed registration, starting with admins.

Step 6: Reduce password use

Over time, stop asking users for passwords at all for supported scenarios. Some organizations move to long random passwords users never see.

Common mistakes

Forgetting account recovery — lost devices need a secure re-onboarding path.
Leaving SMS available as a fallback that undermines the stronger methods.
