Researchers Uncover 39 Attack Methods Against Passkey Authentication Systems

A comprehensive security analysis has documented 39 distinct techniques to compromise passkey-based authentication without breaking underlying FIDO2…

Review how passkeys are implemented in your infrastructure and validate that recovery flows, credential sync, and authentication confirmation include layered controls. Consider multi-factor authentication across critical operations and monitoring for suspicious patterns, even with passkeys in place. Monitor the research team's follow-up publications for specific mitigation guidance.
