TL;DR: Passwordless authentication works best when it is unified across devices and applications, because fragmented login paths increase friction, encourage workarounds, and weaken zero-trust posture, according to Axiad. The governance issue is not whether passwords disappear, but whether identity controls remain coherent enough to support consistent access decisions.
Editorial analysis by NHI Mgmt Group, based on content published by Axiad: “Why the Best Passwordless Authentication Solution Must Be a Unified One”.
Key questions
Q: How should organisations implement passwordless authentication without fragmenting access policy?
A: Organisations should treat passwordless as a unified access programme, not a collection of app-specific features.
Q: When does passwordless authentication create more risk than it reduces?
A: It creates more risk when organisations adopt it without strong device governance, fallback controls, or recovery rules.
Q: What breaks when passwordless is rolled out to only part of an application estate?
A: Users and support teams end up operating under two authentication models at once.
Practitioner guidance
- Standardise passwordless policy across applications Define one assurance model for passwordless access so mobile, desktop, and shared enterprise apps do not each invent their own rules.
- Anchor passwordless rollout in SSO Use single sign-on as the common entry point where possible so passwordless methods are enforced through one authentication path.
- Limit the number of passwordless variants per workforce segment Avoid mixing too many device-based, biometric, and behavioral paths for the same user population unless there is a clear policy reason.
Bottom line: Passwordless only strengthens zero trust when it is consistent enough to be used everywhere the business needs it.

Unified passwordless is a governance requirement, not a convenience feature. The article's core point is that passwordless only improves security when users can rely on the same identity path across applications and devices. If the organisation tolerates multiple, incompatible login experiences, it creates the conditions for bypass behaviour and inconsistent assurance. The practical conclusion is that authentication modernisation has to be governed as a programme, not deployed as isolated point solutions.
A few things that frame the scale:
- eBay's passkey data shows 55-60% of passkey adoption happens on mobile, against around 20% on desktop.
A question worth separating out:
Q: How do you know if unified passwordless is actually working?
A: Look for fewer login workarounds, fewer help desk resets, and fewer exceptions between devices and applications. If users still need alternative paths for common tasks, the programme has not achieved true unification. A working model should feel simpler to users while remaining consistent for the security team.
