Why Passkey Chrome can still be penetrated? This is a security vulnerability and how to solve it
Summary
- The root of the security vulnerability The private key (private key) passkey is encrypted, but malware InfoStealer Can hijack a session cookie or exploit the OS local verification mechanism before authentication is complete.
- Main user risks: If the physical device or OS is successfully compromised, the hacker can bypass the Chrome password manager protection without the need to decrypt the credentials directly.
- Main solution: Implement layered protection through local key encryption (TPM), clean session cookies regularly, and use separate physical security keys for crucial accounts.
Dissecting Passkey and Password Manager Security Locks in Google Chrome
The transition of the technology industry from conventional passwords to technology Passkey based on Fido2 standards and WebAuthn is predicted to be the end of the era Phishing. However, the latest findings from the Lidahtekno editorial team show that the Google Chrome default password manager ecosystem is not completely immune from the threat of modern hacking.
Architecturally, Passkey stores cryptographic key pairs: public keys in application servers and private keys inside the device’s secure storage space (such as Google Password Manager credentials). The security gap does not lie in its cryptographic mathematics, but at the turning point of system integrationEndpoint vulnerabilities). Based on the results of cybersecurity research, hackers take advantage of the loophole of hardware and malware data thievesInfoStealer) to bypass chrome biometric authentication.
When a computer or mobile device is exposed to malware, the hacker can manipulate the browser API to duplicate the verified access tokens. This makes the hacker able to log into the victim’s account without the need to crack the passkey encryption itself.
Passkey vs conventional password: security threat analysis
To understand the position of Passkey protection in Google Chrome, the comparison table below outlines the risk matrix of the various authentication methods commonly used today:
| Security parameters | Google Chrome Passkey | conventional password | Third party password manager |
|---|---|---|---|
| Resistance to phishing | very high (domain locked) | Very low | High |
| vulnerability to the infostealer | Medium (Session Token Exploitation) | very high (plaintext theft) | low (need master password) |
| Physical access protection | depending on the pin/biometric OS | None (if auto-fill is active) | Depends on the master key / standalone encryption |
| Cryptographic Key Isolation | stored in Hardware Enclave/TPM | No private key encryption | End-to-end vault encryption |
A handy guide to securing Passkey and Chrome account from hacking gaps
Adapted from the Risk Mitigation Guide for the Lidahtekno Editorial Team, here is a step-by-step guide to locking the security of Google Chrome to avoid the exploitation of Passkey:
- Enable Advanced Safe Browsing feature: Open the menu chrome settings > privacy and security > Security, then select Options Enhanced protection (enhanced protection) To block InfoStealer malware downloads in real-time.
- Require biometric authentication when auto-fill: Go to setting > Password Manager > Suit, then activate the option Use biometrics when filling in password/passkey So that local hackers can’t automatically perform authentication.
- Update TPM module and operating system: Make sure the driver Trusted Platform Module (TPM 2.0) On Windows or Secure Enclave on macOS/Android is always updated to ensure physical isolation of the passkey private key.
- Use the Chrome On-Device Encryption feature: Enable the built-in encryption key (on-device encryption) in your Google account so that the password and passkey data synchronized in the cloud are transcribed with end-to-end encryption without being accessible to any party.
- Perform periodic cleaning of active sessions: Access the Google account control page, check the connected devices list, and click Sign out In unused foreign browser sessions to cut off access to potentially stolen tokens.
Recommendation for Lidahtekno Editor
Although Passkey technology is much safer than traditional passwords, relying on browser default managers without an additional layer of defense remains at risk. Users are advised to separate the credentials of vital accounts—such as banking and key emails—by combining the use of a Fido2-based physical security key (such as Yubikey) to achieve maximum protection against browser session leaks.
