What breaks when organisations skip identity verification before passkey issuance?

The control that breaks is assurance. A passkey may be technically valid and resistant to phishing, yet still be issued to the wrong subject or under weak proofing conditions. That creates a durable trust problem because the credential looks strong while the identity behind it was never adequately confirmed.

Why This Matters for Security Teams

Skipping identity verification before passkey issuance breaks the assurance model, not the cryptography. A passkey can still resist phishing and replay, but if the enrolment path is weak, the organisation has only issued a strong credential to an unverified subject. That creates durable risk because later access reviews tend to trust the credential format instead of the original proofing step.

This is especially dangerous in environments that assume passkeys automatically solve identity risk. Current guidance increasingly treats enrolment assurance as a separate control from authentication strength, which is why identity proofing, recovery, and issuance governance must be designed together. NHIMG research on Ultimate Guide to NHIs shows how often organisations still lose track of identity assurance once credentials enter the lifecycle, and public breach analyses such as 52 NHI Breaches Analysis show that weak issuance and poor governance tend to surface only after abuse has already begun.

In practice, many security teams encounter this only after a valid-looking passkey has already been bound to the wrong account or recovery path, rather than through intentional proofing failure testing.

How It Works in Practice

Passkey issuance should be treated as a trust-gating event. The organisation first verifies the subject, then binds a public key to that verified identity, and then governs recovery, re-enrolment, and revocation under the same assurance policy. If proofing is skipped or reduced to a low-friction email check, the passkey may still work perfectly, but the system has no reliable basis for asserting who received it.

That distinction matters because passkeys authenticate possession of a private key, not truth of identity. A stolen, substituted, or weakly recovered account can inherit a passkey that looks more trustworthy than the underlying enrolment ever was. NIST digital identity guidance and the evolving European identity stack both separate identity proofing from authenticator strength, which is why frameworks such as eIDAS 2.0 matter when organisations design high-assurance issuance flows.

• Use verified identity proofing before enrolment, not after the authenticator is already active.
• Bind passkeys to the intended account owner with step-up checks for high-risk issuance.
• Apply stronger recovery controls than initial registration, because recovery is often the weakest trust path.
• Log evidence of proofing, issuance, and re-binding so assurance can be audited later.
• Reassess issuance rules for privileged, regulated, or delegated accounts where misbinding has outsized impact.

For NHI-heavy environments, the same pattern shows up when service accounts, API consumers, or automation principals are granted durable trust without clear origin assurance. NHIMG guidance in the Ultimate Guide to NHIs and issue-oriented research like Top 10 NHI Issues both reinforce that lifecycle controls are only as strong as the identity check that starts them.

These controls tend to break down when self-service enrolment, delegated admin, or bulk provisioning bypasses human review because the organisation optimises for speed over assurance.

Common Variations and Edge Cases

Tighter identity proofing often increases onboarding friction, requiring organisations to balance fraud resistance against user experience and support cost. That tradeoff is real, especially for consumer-facing apps, partner ecosystems, and fast-moving developer platforms where repeated verification can create abandonment.

Best practice is evolving, but there is no universal standard for every issuance scenario. High-risk accounts should generally use stronger proofing, stronger recovery, and explicit re-authentication before credential binding. Lower-risk internal use cases may accept lighter proofing, but only if the organisation is explicit about what level of assurance the passkey does and does not provide. The key mistake is letting a strong authenticator silently imply strong identity.

For regulated onboarding, organisations may need to align passkey issuance with KYC-like controls, especially where account fraud, financial access, or delegated authority are in scope. For machine identities, the equivalent problem is not a person failing proofing but a workload being issued trust without verifiable origin or ownership. That is why the same governance instinct appears in breach reporting such as Cisco DevHub NHI breach and why identity-first design should be applied before any durable credential is minted.
