Passkeys improve an important part of the access journey: proving possession of a cryptographic credential without relying on a reusable password. That can reduce phishing exposure and make sign-in easier. It does not determine whether the account should exist, which access it should hold or whether that access remains appropriate.
Authentication is one control plane
Authentication answers a focused question: can this subject prove control of an accepted credential? Identity governance addresses a broader set of questions:
- Who created and owns the identity?
- Which roles and entitlements are justified?
- What happens when responsibilities change?
- Who reviews exceptional or privileged access?
- When should access be removed?
A strong authenticator attached to an over-privileged or abandoned account simply provides strong access to the wrong permissions.
Design the complete lifecycle
Passwordless programmes work best when they are connected to authoritative identity data and lifecycle events. Joiner, mover and leaver processes should remain clear. Credential registration and recovery need policy. Device loss, account recovery and delegated administration require the same architectural attention as the primary sign-in ceremony.
| Capability | Primary question |
|---|---|
| Passkey authentication | Can the user prove control of the credential? |
| Identity lifecycle | Should the identity exist? |
| Access governance | Should this identity have this access? |
| Privileged access | Under what conditions can elevated access be used? |
A joined-up architecture
Treat passkeys as part of an identity security system rather than a standalone feature. Connect registration policy, device posture, recovery, access reviews, privileged controls and monitoring. Use risk-based exceptions without allowing temporary workarounds to become permanent architecture.
Better authentication reduces one class of risk; governance prevents access from becoming unjustified over time.
Measure the right outcomes
Useful measures should cover more than enrolment. Consider the reliability of recovery, the reduction of weak authentication paths, the removal of dormant access and the time required to revoke credentials after a lifecycle event.
