GoKawiilResearchers Catalog 39 Attack Techniques Targeting Passkey Systems
Security researchers, including work from SpecterOps, have documented at least 39 distinct methods that can undermine passkey authentication despite the underlying FIDO2 cryptography remaining secure. These techniques target the surrounding infrastructure rather than the cryptographic keys themselves, including browsers, operating systems, password managers, sync services, Bluetooth transport, and account recovery workflows. Many have working proof-of-concept tools, and some techniques are already surfacing in real-world attack activity.
