HKLM\Software\Policies\Google\Chrome
Controls the state of the Device Bound Session Credentials feature. Device Bound Session Credentials protects Google authentication cookies against cookie theft by regularly providing a cryptographic proof of device possession to Google servers. If this policy is set to false, Device Bound Session Credentials feature will be disabled. If this policy is set to true, Device Bound Session Credentials feature will be enabled. If this policy is unset, Google Chrome will follow the default rollout process for the Device Bound Session Credentials feature, which means that the feature will be gradually rolled out to an increasing number of users.
