Researchers have identified 39 different methods that can compromise passkey authentication, which is designed to replace traditional passwords and reduce security risks. These methods exploit various aspects of the authentication process, including how prompts are presented, how credentials are synced, and how users enroll or recover their accounts. Notably, these vulnerabilities do not break the underlying FIDO2 cryptography, meaning the attacks are focused on misusing the authentication framework rather than cracking it outright. This discovery is significant as it shows that while passkeys are a step forward in security, they are not foolproof and can still be vulnerable to sophisticated attacks. Users and organizations adopting passkey systems need to be aware of these risks and implement additional security measures to protect against potential exploitation.
