New Passkey Attacks Can Recover Synced Private Keys or Bypass Phishing-Resistant MFA
August 10, 2026 · The Hacker News · Severity: HIGH
Three separate research efforts showed ways to bypass passkey protections without compromising the underlying cryptography. Passkeys, intended to replace passwords and resist phishing, were found vulnerable to new attack vectors.
Key Takeaways
- Researchers demonstrated three methods to defeat passkey protections without breaking cryptography.
- Passkeys designed to replace passwords and resist phishing are not invulnerable.
- These attacks highlight the need for robust passkey implementation and awareness.
