Google Chrome's New DBSC Feature: A Leap Forward in Browser Security
In May 2026, Google announced the general availability of Device Bound Session Credentials (DBSC) in Chrome, a security feature designed to prevent session cookie theft. DBSC cryptographically binds session cookies to a user's device using hardware-backed security modules like the Trusted Platform Module (TPM) on Windows and the Secure Enclave on macOS. This binding ensures that even if session cookies are exfiltrated, they cannot be used on unauthorized devices, thereby mitigating risks associated with session hijacking and account takeovers. ([developer.chrome.com](https://developer.chrome.com/docs/web-platform/device-bound-session-credentials?hl=en&utm_source=openai)) The introduction of DBSC addresses the growing threat posed by infostealer malware, which has been increasingly used to extract session cookies and bypass multi-factor authentication. By implementing DBSC, Google enhances user security by proactively preventing unauthorized access through stolen session cookies, marking a significant advancement in browser security measures.
