  • Engineer — Learn: Novel attack taxonomy spanning enrollment, credential sync, recovery, and prompt abuse—none break FIDO2 crypto but all exploit surrounding trust boundaries. Use this to audit your passkey rollout design and recovery flow assumptions; no patch or config change is required today.
  • SOC/IR — Learn: No active exploitation, IOCs, or ATT&CK-mapped TTPs are present, but understanding these authentication-layer abuse paths could sharpen future detection logic around anomalous passkey enrollment and recovery events.
  • Leader — Plan: If the organization is actively deploying or roadmapping passkeys, this research warrants a review of vendor implementation choices and recovery-path risk this quarter—39 documented bypass methods is a meaningful input to a passkey adoption strategy.
