TL;DR: Passkeys reduce password theft and credential-stuffing exposure in Auth0-based logins by shifting authentication to device-bound biometrics and OIDC federation, according to Descope. The governance question is no longer whether passwords are weaker, but how identity teams control account linking, profile sync, and recovery paths without creating duplicate or hijacked identities.

Questions worth separating out
Q: How should security teams roll out passkeys without breaking account recovery?
A: Start with low-risk journeys, then define recovery as a controlled identity workflow rather than a convenience feature.
Q: Why do passwordless systems still need identity governance?
A: Passwordless systems still need identity governance because authentication strength does not answer lifecycle questions.
Q: What do organisations get wrong when they treat passkeys as a full password replacement?
A: They assume the cryptography solves the governance problem.
Practitioner guidance
- Define account linking rules before rollout Require a verified existing identity path before a new passkey can be associated with an account, and document when manual approval is needed for linking.
- Validate OIDC trust settings end to end Review issuer, client credentials, and scope definitions as privileged federation controls, and test that token claims map to the intended user record.
- Synchronise profile attributes at login Enable controlled profile synchronisation so users do not create duplicate accounts across authentication methods, and monitor for mismatched attributes after first login.

Passkeys solve password theft, but they do not solve identity governance. The control removes reusable secrets from the primary login path, which lowers exposure to phishing and credential stuffing. But the real governance burden shifts to federation assurance, account linking, and recovery because those are now the places where identity compromise can be introduced. The practitioner conclusion is that passwordless authentication must be governed as an access lifecycle problem, not only an authentication problem.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to Ultimate Guide to NHIs.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.
A question worth separating out:
Q: How do IAM teams decide where passkeys should be mandatory first?
A: Start with applications that have high phishing exposure, strong user support demand, or repeated password reset activity. Then prioritise use cases where account recovery is already well governed, because passkeys work best when the surrounding identity proofing process is already stable.
