The passwordless maturity model is a staged framework for moving from password-based access to environments where passwords are masked or removed. It helps organisations adopt passwordless methods gradually, rather than forcing a full cutover at once. In healthcare, it supports realistic sequencing across clinical and non-clinical workflows.
What the passwordless maturity model measures
A passwordless maturity model is not just a rollout plan, it is a way to assess where an organisation sits on the path from password dependence toward stronger, less-friction sign-in. It helps teams separate early pilots from scaled adoption and from environments where passwords are no longer the primary user secret.
The model usually reflects practical checkpoints such as whether passwords still exist behind the scenes, whether users can sign in with phishing-resistant methods, and whether recovery, enrollment, and fallback paths are as mature as the primary sign-in method.
How maturity progresses in real environments
Most organisations move through stages rather than jumping straight to full password removal. Early stages often reduce password visibility with federation or single sign-on, while later stages expand passkeys or other passwordless methods across more user groups and applications.
That staged approach matters because authentication is an ecosystem, not a single control. A mature program has to account for identity proofing, authenticators, device support, account recovery, and exception handling across both high-risk and low-risk workflows. NHIMG’s Passwordless and Passkeys Guide is a useful companion for understanding how passkeys, FIDO2, and phishing-resistant sign-in fit into that progression.
In practice, maturity is often uneven. An organisation may support passwordless access for workforce apps but still rely on passwords for legacy systems, service desks, or recovery flows. A meaningful model captures that unevenness instead of treating “passwordless” as a binary label.
What a mature passwordless state looks like
Higher maturity means passwordless methods are available in the places that matter most, and the remaining password dependencies are clearly understood. The goal is not merely to add a new login option, but to reduce exposure to password spraying, phishing, and help-desk driven account takeover.
A strong model also recognises that authentication quality depends on the surrounding controls. For example, passkeys, FIDO2 security keys, and device-bound authenticators are materially stronger when enrollment, recovery, and step-up authentication are designed to avoid weak fallback paths. The NIST SP 800-63 Digital Identity Guidelines provide the main reference point for phishing-resistant authenticators, assurance levels, and modern authentication expectations.
At the mature end, passwordless is no longer a special project. It becomes the default sign-in pattern, with exceptions managed explicitly rather than tolerated informally.
Why maturity models help adoption and governance
Passwordless programs often fail when organisations try to treat them as a one-time technology swap. A maturity model gives security, identity, and operations teams a shared language for sequencing adoption, prioritising the right user populations, and deciding where policy, UX, and recovery design need improvement.
That structure is especially useful when the programme spans multiple application types and user groups. The model helps teams decide when to expand from pilots to broader rollout, when to retire weak fallback methods, and when to formalise standards for onboarding, device trust, and recovery.
For teams that want to compare maturity approaches, OWASP SAMM is a helpful reference for the general idea of staged security maturity, even though passwordless is an identity-specific use case. NHIMG’s Identity Security Maturity Model is also relevant because it places authentication, lifecycle, and access governance inside a broader identity capability view.
Risk and Threat Considerations
Weak passwordless maturity can create a false sense of progress. Organisations may modernise the sign-in screen while leaving recovery, fallback, or legacy access paths exposed, which keeps phishing, social engineering, and account takeover risks alive.
Failure mechanism: Attackers often target the weakest remaining route into the identity system, such as password reset, help-desk recovery, SMS fallback, or unmanaged legacy applications that still accept passwords.
Impact: The result can be credential theft, session compromise, or broader account takeover even when the primary sign-in method appears modern and secure.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-63, OWASP SAMM and NIST SP 800-53 Rev 5 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | AAL — Authenticator Assurance Levels | Passwordless maturity centers on phishing-resistant authenticators and assurance level progression. |
| Recommendation — Map each rollout stage to the required assurance level and prefer phishing-resistant authenticators for higher-risk access. | ||
| OWASP SAMM | GOVERNANCE — Governance | Passwordless adoption is a staged maturity journey that needs governance, measurement, and sequencing. |
| Recommendation — Use SAMM-style maturity checkpoints to track adoption, recovery readiness, and exception handling. | ||
| NIST SP 800-53 Rev 5 | IA-2 — Identification and Authentication (Organizational Users) | Passwordless rollout changes how organisational users are authenticated across the access lifecycle. |
| IA-5 — Authenticator Management | Maturity depends on issuing, protecting, rotating, and retiring authenticators and fallback secrets. | |
| AC-7 — Unsuccessful Logon Attempts | Passwordless reduces exposure to repeated password guessing and related account abuse. | |
| Recommendation — Require stronger authenticators and reduce password dependence for organisational user access. Tighten authenticator lifecycle controls and remove weak recovery dependencies. Retain lockout and abuse-detection controls for any residual password-based access paths. | ||
Practitioner Guidance
Governance implication: Treat passwordless maturity as an end-to-end control program, not just a deployment metric. The most important question is whether the fallback and recovery paths are as intentional and defensible as the primary passwordless method.
Practitioner note: The best maturity models make exceptions visible. If a system, population, or recovery flow still requires passwords, that dependency should be measured and managed rather than hidden inside a “passwordless” label.
