The browser gives you NotAllowedError. It won't say whether the user canceled, the prompt timed out or the platform was not ready. Passkey Errors classifies every failure by stage, type and platform.
Failures classified by stage and error type
Time-to-fail and recovery rate per error
From any error cluster to the affected flows
Classify first, then fix
Passkey Errors quantifies failure patterns across your whole traffic. When one user writes in, User Debugging replays their exact journey.
WebAuthn reports one exception for a dozen causes. Classifying it by journey stage makes it actionable.
Readiness decides the split: which failures are your bug and which are just the platform.
An error most recover from is friction. One nobody recovers from ends sessions. Recovery rate tells them apart.
Three views: where a failure happened, its type and whether users recovered.
One journey diagram for every passkey login, from readiness to completion. Inspect any node for its flows.
