39 ATTACK METHODS FOUND IN PASSKEY SYSTEMS

While passkeys eliminate many traditional password-based attacks, the authentication systems built around them contain multiple vulnerabilities. Researchers documented attacks targeting authentication prompts, synced credentials, enrollment processes, and account recovery mechanisms. The findings reveal that attackers can exploit trust boundaries and implementation gaps without breaking the cryptographic foundation of FIDO2. Vulnerable areas include how credentials are synchronized across devices, how users enroll in passkey systems, and how accounts are recovered when access is lost. These discoveries highlight a critical distinction: passkeys provide stronger cryptography than passwords, but the broader authentication infrastructure surrounding them requires careful security design. Organizations implementing passkey systems must address these implementation-level vulnerabilities to realize the full security benefits. The research underscores that cryptographic strength alone does not guarantee secure authentication systems.
