Pass the Passkey: A Novel Attack Surface in Passwordless Authentication


This article analyzes new attack classes against passwordless authentication, focusing on Google’s synced passkey ecosystem and the Cloud Authenticator used by desktop clients. The attacks demonstrate how malware on a compromised endpoint can misuse onboarding, recovery and device trust workflows to take over passkey-protected accounts. Palo Alto Unit 42 shows how an attacker can authenticate without user interaction, bypass user verification requirements and extract all synced passkey private keys.

After decades of breaches and billions in losses, the attack vectors that defined the era of passwords and shared secrets are finally starting to fade. Passkeys replace passwords and traditional multi-factor authentication (MFA) with public-key cryptography, decreasing entire classes of attacks that have dominated the threat landscape for years.

With no shared secret to steal, reuse or phish, many of an attacker’s most reliable tools are becoming obsolete. This represents a significant disruption for the credential theft market.
