New Passkey Attacks Can Recover Synced Private Keys or Bypass Phishing-Resistant MFA
Researchers have demonstrated three separate attacks that can defeat passkey protections without breaking the underlying cryptography, including reusing signed authentication material and abusing cloud-synced passkey systems. These attacks can potentially recover synced private keys or bypass phishing-resistant multi-factor authentication (MFA). The passkey system is designed to replace reusable passwords and resist phishing attempts.
Why it matters: Practitioners using passkey protections, especially those with cloud-synced systems, should be aware of these vulnerabilities and take steps to mitigate them to prevent potential private key exposure or MFA bypass.

New Passkey Attacks Can Recover Synced Private Keys or Bypass Phishing-Resistant MFA
Three separate research efforts disclosed attacks that circumvent passkey protections by reusing exposed authentication material from Windows, exploiting cloud-synced passkey systems from compromised devices, and leveraging additional attack vectors. These attacks defeat passkey security without breaking the underlying cryptography. Passkeys are promoted as replacements for passwords and as phishing-resistant, but these findings expose practical weaknesses in their implementation and deployment.
Why it matters: Security teams deploying passkeys as a primary authentication defense need to understand that implementation flaws, device compromise, and signed material exposure can undermine their phishing-resistance claims; practitioners should review how passkeys are synced, stored, and validated in their environments.
