Chromium OS - User Accounts and ManagementPicker Weng
The Chromium OS device includes many configurations such as network, whitelist, bookmark, themes, and etc. We can simply distinguish these settings between system settings and user preference. In general, every user would like to have own configuration. This means user can define their theme, network configuration, and etc. But user’s data is always stored in the cloud server in the cloud-based device so that we have to sync these data down to device from web. For this reason, the Chromium OS device should know that which user is logging in to device, and then sync his data down to. Therefore, Google’s Chromium OS team develops some mechanism to manage user accounts and settings.
