Separate workflows create avoidable friction, longer provisioning times, and more room for human error during credential setup. Teams often end up duplicating identity checks, repeating admin steps, and slowing onboarding for employees or contractors. A unified orchestration model helps keep assurance consistent while reducing operational overhead and the chance of incomplete enrollment.
Why This Matters for Security Teams
When passkey and smart card enrolment are split into separate workflows, the breakage is usually not the cryptography. It is the identity proofing, admin coordination, and lifecycle handling around it. Separate paths create inconsistent assurance levels, duplicated approvals, and a higher chance that one credential is issued, recorded, or revoked differently from the other. That inconsistency matters because authentication strength is only useful if the enrolment and recovery process is equally controlled.
This becomes even more important in environments that already struggle with credential sprawl. NHIMG notes that 71% of NHIs are not rotated within recommended time frames, and the same operational weakness appears when one credential type is managed carefully while another is handled ad hoc. The result is uneven governance across access methods, which undermines trust in the whole onboarding flow. NIST’s Cybersecurity Framework 2.0 treats identity assurance and access control as operational disciplines, not one-time setup tasks.
In practice, many security teams discover the mismatch only after a user is partially enrolled, help desk queues grow, or emergency exceptions start bypassing the intended process.
How It Works in Practice
A unified enrolment model treats passkeys and smart cards as different authenticators within the same identity lifecycle, rather than as separate projects. The user or contractor proves identity once, the platform records assurance once, and the orchestration layer provisions each credential according to policy, device posture, and role. This is where good workflow design matters more than the token format itself. Current guidance suggests tying both authenticators to the same authoritative identity record, the same audit trail, and the same revocation event.
Practically, that means the workflow should handle:
- One identity proofing step with shared evidence capture
- Policy-driven issuance for passkeys, smart cards, or both
- Centralized logging of enrolment, recovery, and deprovisioning actions
- Consistent binding of credentials to the same subject and assurance level
- Automatic revocation or suspension when employment status changes
For non-human or privileged operational accounts, the same principle applies: do not let different enrolment paths produce different governance outcomes. The Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and the NHI Lifecycle Management Guide both reinforce the broader lesson: lifecycle consistency reduces drift, especially when multiple authenticators or credentials must remain aligned.
Teams that automate enrolment routing through a single identity platform also reduce duplicate admin effort and make it easier to prove who received what, when, and under which approval path. These controls tend to break down in mergers, regulated sectors, and contractor-heavy environments because identity stores, enrollment rules, and help desk procedures are often inherited from different systems.
Common Variations and Edge Cases
Tighter enrolment controls often increase operational overhead, requiring organisations to balance assurance against onboarding speed. That tradeoff is real, especially where workers need fast device setup, remote access, or temporary credentials. Best practice is evolving, and there is no universal standard for how much of the smart card and passkey workflow must be identical, but the policy outcome should be consistent: one identity, one assurance record, one revocation path.
Some environments may still need separate user journeys for legacy card readers, high-assurance administrative access, or jurisdictions that impose specific proofing requirements. In those cases, the workflows can differ at the interface level while still sharing the same authoritative controls behind the scenes. The operational risk appears when separation leaks into governance, so one workflow gets stronger vetting, better revocation, or cleaner audit evidence than the other.
NHIMG research on the Top 10 NHI Issues and the Ultimate Guide to NHIs — Regulatory and Audit Perspectives shows why this matters operationally: weak lifecycle alignment creates audit gaps, incomplete offboarding, and inconsistent control evidence. Those gaps become especially visible when a credential is replaced, a user role changes, or a recovery event needs to be traced across multiple systems.
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 address the attack and risk surface, while NIST CSF 2.0, NIST SP 800-63, NIST Zero Trust (SP 800-207) and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | PR.AC-1 | Separate enrolment workflows weaken consistent identity assurance and access control. |
| NIST SP 800-63 | Identity proofing and authenticator binding must stay aligned across enrolment paths. | |
| NIST Zero Trust (SP 800-207) | Zero Trust depends on consistent identity signals, not fragmented onboarding workflows. | |
| OWASP Non-Human Identity Top 10 | NHI-01 | Separate enrolment can create lifecycle drift and inconsistent credential governance. |
| NIST AI RMF | Workflow consistency supports trustworthy governance for automated identity operations. |
Standardize proofing and authenticator binding so both credentials inherit the same assurance level.
