Passkey Panic: How Hackers Bypass ‘Phishing-Proof’ Security with a Clever Browser Trick!
Even passkeys aren’t safe from sneaky hackers! SquareX researchers showed how a compromised browser can bypass passkey security. Just a malicious extension or vulnerable website, and bam—access granted. Despite being phishing-resistant, passkeys can be outfoxed. Who knew cyber trickery could be so crafty?

Hot Take:
Well, well, well, looks like even passkeys aren’t as invincible as we thought. Just when you were about to say goodbye to passwords forever, SquareX comes along with a not-so-rosy reminder that even the seemingly secure passkeys can be bypassed with a little help from our sneaky friend, JavaScript. So, while you were busy perfecting your fingerprint scan, hackers were perfecting their browser manipulation skills. Ain’t that a kick in the authentication?
Key Points:
- Passkeys offer a more secure alternative to passwords with methods like PIN, facial recognition, or fingerprint scan.
- SquareX researchers demonstrated a method to bypass passkeys by compromising the browser environment.
- The attack exploits the WebAuthn standard, targeting the registration and authentication processes.
- A malicious browser extension or a client-side vulnerability like XSS can enable the attack.
- Users can be tricked into downgrading to password-based authentication, allowing attackers to obtain credentials.
