When a user switches between Google ChromeOS devices, the Floating SSO Service will restore the user's web service authentication state from the previous device onto the new device. This is achieved by moving user's cookies across devices.
Setting the policy to Enabled will restore the user's web service authentication state from the user's last used Google ChromeOS device automatically upon login.
Setting the policy to Disabled or leaving it unset will not restore the user's web service authentication state upon login on a different device.
The web service domains blocked from being restored can be configured using the FloatingSsoDomainBlocklist policy, while exceptions to that policy can be configured using the FloatingSsoDomainBlocklistExceptions policy.
If both of these policies are unset, all web service authentications, except Google authentications, will be moved.
