TL;DR: Windows Hello for Business improves passwordless sign-in for Windows users, but Axiad’s analysis shows it does not cover non-Windows systems, RDP, VPN, or many business applications, forcing organisations to rely on additional credentials and controls. The practical issue is not passwordless adoption itself, but the identity gaps left behind when it stops at the edge of the estate.
NHIMG editorial — based on content published by Axiad: It’s time to take your Windows Hello for Business solution to the next level
By the numbers:
- 70% of organisations already granting AI systems more access than human employees.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
Questions worth separating out
Q: How should security teams roll out passwordless authentication without leaving identity gaps?
A: They should treat passwordless as a coverage problem, not a single-product deployment.
Q: Why do passwordless programmes still need machine identity controls?
A: Because strong user authentication does not secure devices, services, or signed business interactions by itself.
Q: What breaks when Windows Hello for Business becomes the only authentication strategy?
A: Coverage breaks first.
Practitioner guidance
- Map passwordless coverage against every access path Inventory Windows, macOS, Linux, VPN, RDP, Azure-connected applications, and third-party business systems, then identify where Windows Hello for Business does not apply and what fallback control is currently in use.
- Define compensating controls for unsupported scenarios Set explicit controls for remote login, non-Windows devices, and non-Azure applications so exceptions do not silently reintroduce passwords or ad hoc authentication methods.
- Extend trust to machine identities and signed workflows Use certificate-based identity for devices and digitally signed email or document workflows where transaction integrity matters, so authentication is not limited to the user login step.
What's in the full article
Axiad's full blog post covers the operational detail this post intentionally leaves for the source:
- Support boundaries for Windows Hello for Business across Windows 10, Azure AD, Office 365, RDP, VPN, macOS, and Linux.
- Implementation examples for pairing passwordless sign-in with digital certificates and cloud-based PKI.
- Guidance on extending authentication into non-Windows use cases and third-party services.
- Examples of certificate-based email and document signing for secure business interactions.

Passwordless adoption fails when it is treated as a single-control program rather than an identity architecture. Windows Hello for Business improves one authentication path, but the article shows that unsupported systems, remote access methods, and non-Azure applications still need governed access. The field should read this as an architecture problem, not a point solution problem. Practitioners should design passwordless as a coverage model, not a product choice.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to Ultimate Guide to NHIs.
- 71% of IT leaders identify phishing as the greatest threat for remote workers, which shows why authentication coverage must extend beyond the workstation.
A question worth separating out:
Q: Who is accountable for the exceptions in a passwordless rollout?
A: IAM, endpoint, and platform teams share accountability because the exceptions usually arise at the boundary between device support, application integration, and remote access design. Governance should require explicit ownership for every unsupported use case, so fallback methods do not become unmanaged permanent controls.
