If organisations delay, they risk keeping passwords in place after users and operating systems have moved on. That creates avoidable friction, weaker user experience, and continued exposure to phishing and credential reuse. It can also make the organisation look outdated to customers and employees who increasingly expect simpler, stronger sign-in methods across devices and services.
Why delayed passkey support becomes a security and experience problem
When users and operating systems move toward passwordless sign-in, delaying passkey support does not preserve the status quo, it prolongs the weakest part of the current one. Passwords remain the fallback, which keeps phishing, credential stuffing, password reuse, and reset workflows in the path of normal access. The longer that gap stays open, the more organisations pay in friction, support load, and avoidable exposure.
Passkeys matter because they shift the authentication burden away from memorised secrets and toward device-bound, phishing-resistant sign-in. That changes the user experience and the attack surface at the same time. If an organisation lags behind platform support, it risks forcing users back into a weaker method even when their browser, phone, or operating system is ready for stronger sign-in.
For practitioners, the real issue is not only whether passkeys are available, but whether the organisation is still treating passwords as the primary control after the ecosystem has already moved on. That mismatch creates a visible gap between user expectation and the sign-in method the business is willing to support.
What actually breaks when passwords remain the default
The first failure is user friction. A password-based journey usually requires more typing, more resets, and more chances for lockout, especially on mobile devices and shared customer journeys. Passkeys reduce that overhead by making authentication feel native to the device instead of dependent on human memory and repeated challenge steps.
The second failure is security drag. Passwords are still attractive to attackers because they can be phished, reused, guessed, or replayed after leakage. If passkeys are delayed, the organisation continues to inherit the same account-takeover pathways even as its users increasingly expect safer, simpler sign-in. That is especially costly where the brand promise depends on modern digital access.
The third failure is adoption debt. Once users become accustomed to passkeys elsewhere, a password-only or password-first service can start to look outdated, clumsy, or even untrustworthy. For customer-facing products, that perception can affect conversion and retention. For workforce use, it can increase resistance to security changes because the organisation appears to be lagging behind the tools people already use in daily life.
How to think about the transition, not just the launch
A passkey rollout should be judged as an access transition, not a feature launch. The important question is whether the organisation can support passkeys without breaking recovery, support, shared-device use, or cross-platform sign-in. If those edge cases are not planned, users will quietly fall back to passwords, and the intended security gain will be diluted.
The best implementation path is to keep the fallback controlled while making the stronger option the easiest one. That means measuring how many sign-ins still depend on passwords, how often resets are needed, and where users abandon the sign-in flow. It also means keeping enrollment simple enough that support teams are not forced to steer users back to legacy methods just to close tickets quickly.
Organisations that are serious about stronger authentication should align the transition with a broader identity strategy. NHIMG’s Workforce Identity Security Guide is useful here because it connects phishing-resistant MFA, passkeys, SSO, help desk recovery, and session theft into one operational picture. For the user experience side of the migration, the standard itself is also important, especially when the organisation needs a reference point for phishing-resistant authentication and device-bound credentials, as described in NIST SP 800-63 Digital Identity Guidelines.
Risk and Threat Considerations
Delaying passkey support extends the lifetime of password-based abuse paths, so the main risk is not theoretical. Phishing, credential stuffing, and password reuse continue to work while the organisation waits for a cleaner migration window. That creates a gap where users expect modern sign-in but the environment still depends on older, more attackable methods.
Failure mechanism: The organisation keeps passwords in the authentication path after users and platforms have moved to passwordless options, which preserves phishing and reuse exposure and encourages fallback behaviour.
Impact: Account takeover risk remains higher than necessary, support effort stays elevated, and the service can lose trust with users who expect stronger, simpler sign-in.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 addresses the attack surface, NIST SP 800-63, CIS Controls v8 and NIST SP 800-53 Rev 5 set the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital Identity Guidelines | Passkeys and phishing-resistant authentication are central to digital identity assurance. |
| Recommendation — Adopt phishing-resistant authenticators and align recovery with assurance requirements. | ||
| OWASP Non-Human Identity Top 10 | NHI-04 — Insecure Authentication | Delayed passkey support keeps weaker authentication paths in use and preserves phishing exposure. |
| Recommendation — Prioritise phishing-resistant authentication over password-only fallback paths. | ||
| CIS Controls v8 | CIS-6 — Access Control Management | Transitioning away from passwords requires controlled account and access handling during sign-in changes. |
| Recommendation — Review authentication pathways and remove unnecessary password-based access. | ||
| NIST SP 800-53 Rev 5 | IA-2 — Identification and Authentication (Organizational Users) | Workforce sign-in is directly affected when passwords remain the default over stronger authenticators. |
| Recommendation — Use phishing-resistant authenticators for organizational user access. | ||
| ISO/IEC 27001:2022 | A.5.17 — Authentication information | Passkey adoption changes how authentication information is issued, protected, and recovered. |
| Recommendation — Protect authentication information and reduce reliance on reusable passwords. | ||
Practitioner Guidance
What to verify: Confirm whether passkeys are available for the full sign-in path, not just a pilot group or a secondary channel. The test is whether a typical user can enroll, sign in, recover access, and complete support-assisted recovery without being forced back to passwords as the normal answer.
Decision rule: If the organisation already supports the platforms its users rely on, treat continued password primacy as a design choice that needs a clear rationale, not as an interim state. If password fallback is still required, keep it narrow, visible, and easy to measure so it does not silently become the default.
Practitioner takeaway: The goal is not to eliminate every legacy option at once, it is to avoid making passwords the long-term control by inertia after the ecosystem has already moved to stronger, lower-friction sign-in.
