Privileged users and high-risk accounts should be first in line because their access carries greater impact if compromised. Requiring passkeys for those roles ensures the strongest control is applied where the downgrade cost is highest and where weaker fallback options are least defensible.
Why This Matters for Security Teams
Passkeys are not just a phishing-resistant login upgrade. In an identity programme, the first rollout decision should follow blast radius, not convenience. Privileged users, administrators, developers with production access, and service owners are the accounts most likely to turn a compromise into material impact. That is why high-risk identities should be first in line for passkeys, especially where password reuse, MFA fatigue, or fallback recovery paths still exist.
The practical concern is that many organisations treat passkey adoption as a broad usability project, then discover the hard cases only after a weak account becomes the entry point. NHI Management Group’s research shows that secrets and identity failures rarely stay isolated: the Ultimate Guide to NHIs notes that 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, which is a reminder that high-value access tends to be the real target, not the average user session. The NIST Cybersecurity Framework 2.0 reinforces the need to prioritise safeguards around critical assets and access paths rather than applying controls uniformly.
In practice, many security teams encounter weak fallback authentication only after a privileged account has already been used to change the control plane.
How It Works in Practice
A sensible rollout starts by ranking identities by privilege, business criticality, and recovery risk. Passkeys should move first into administrator accounts, cloud console access, production support roles, and any user population whose compromise could expose secrets, alter policies, or disable logging. The intent is to reduce the probability that the most sensitive identities can be phished, replayed, or coerced through password reset workflows.
Operationally, the programme works best when passkeys are paired with tighter account recovery and stronger enrolment standards. If a user can simply fall back to SMS, email-based reset, or weak help-desk verification, the security gain is limited. Current guidance suggests treating recovery as part of the authentication design, not an afterthought. For enterprises with mixed device fleets, implement passkeys where device binding and platform support are strongest first, then expand coverage as assurance and support maturity improve.
- Start with privileged admins, break-glass accounts, and production operators.
- Require passkeys for access to code repositories, CI/CD, cloud control planes, and secrets tooling.
- Remove weak fallback paths before broadening to lower-risk populations.
- Use conditional access to block step-down authentication for sensitive systems.
This priority model aligns with NHI governance lessons in the Top 10 NHI Issues and the 52 NHI Breaches Analysis, where over-permissioned or poorly protected identities repeatedly amplify incidents. Passkeys do not fix over-privilege, but they do reduce the likelihood that an attacker can leverage a stolen secret or password to reach the systems that matter most. These controls tend to break down in environments with shared admin accounts, unsupported legacy applications, or recovery processes that still depend on manually trusted help-desk intervention because the strongest login control is then bypassed at the weakest operational link.
Common Variations and Edge Cases
Tighter passkey rollout often increases support effort, device management complexity, and account recovery governance, so organisations have to balance stronger assurance against operational friction. That tradeoff is especially real in enterprises with contractors, BYOD programmes, or regulated legacy workloads where passkeys cannot yet be enforced everywhere.
There is no universal standard for sequencing every user population, but best practice is evolving around risk-based prioritisation. Some organisations may start with finance or executive users, while others will prioritise cloud engineers, SOC analysts, or anyone with access to privileged tooling. The key is that “first” should mean highest impact, not highest visibility.
Edge cases matter. Shared accounts should be eliminated or reworked before passkey enforcement can be meaningful. Break-glass access usually needs a separate, tightly controlled path with documented emergency use. Service accounts and machine identities are a different problem altogether: passkeys are not the control for those, and organisations should not confuse human authentication rollout with NHI hardening. The strongest programmes sequence passkeys alongside privileged access review, recovery hardening, and removal of legacy bypass routes. In environments with immature identity inventory, unsupported endpoints, or broad use of external contractors, passkey enforcement often stalls because the exception list becomes larger than the policy itself.
