Chrome secures sessions by binding cookies to hardware, thwarting infostealer theft
Google Chrome 146 on Windows adds Device Bound Session Credentials (DBSC), cryptographically linking a user’s session to the device’s hardware (TPM on Windows, Secure Enclave on macOS) so stolen session cookies can’t be exploited. New short-lived cookies require possession of the hardware-bound private key, otherwise they expire quickly. macOS support is planned for a future Chrome release. The DBSC protocol, developed with Microsoft and tested with partners like Okta, aims to reduce cookie theft while preserving privacy, with implementation guidance and W3C specs available for developers.
