TL;DR: Synced passkeys usually prevent lockout after device loss, but weak fallback recovery such as email or SMS OTP is where assurance breaks down, according to Authsignal. Recovery paths need their own assurance level so authentication does not weaken after a lost device.
Editorial analysis by NHI Mgmt Group, based on content published by Authsignal: “What happens when your passkey device is lost? Understanding recovery and device sync”.
Key questions
Q: Why do insecure recovery methods weaken the protection that passkeys are supposed to provide?
A: Passkeys reduce phishing risk only when the whole authentication flow stays phishing resistant.
Q: What are the signs that passkey recovery is failing in an organisation?
A: Common warning signs include frequent support tickets after device loss, users depending on a single recovery path, and accounts that cannot be restored without manual intervention.
Q: When does passkey recovery become a security weakness instead of a convenience?
A: Passkey recovery becomes a weakness when the fallback channel is easier to abuse than the passkey itself.
Practitioner guidance
- Define recovery assurance targets Set the minimum identity assurance required for passkey recovery and align it with the assurance level of the primary sign-in path.
- Remove weak fallback downgrades Review email OTP, SMS OTP, and help-desk recovery as potential downgrade paths.
- Separate ecosystem sync from recovery policy Document which passkey flows rely on ecosystem sync, which rely on cross-device authentication, and which are true account recovery events.
Bottom line: Synced passkeys reduce the chance of lockout, but recovery controls determine whether the authentication programme keeps its assurance after device loss.

Passkey recovery is an authentication governance problem, not a support problem. Device sync reduces the probability of lockout, but it does not remove the need to govern how identity is re-established when a trusted device is gone. The control question shifts from credential possession to recovery assurance, which is a lifecycle issue as much as an authentication issue. Practitioners should treat recovery design as part of the auth architecture, not as an exception path.
A question worth separating out:
Q: Should organisations treat cross-device passkey sign-in and account recovery as the same control?
A: No. Cross-device sign-in is a bridging mechanism between trusted devices, while account recovery is a higher-risk event that re-establishes identity after loss or compromise. Separating those paths lets teams assign the right assurance, logging, and step-up requirements to each one.
