Google has updated Chrome OS with a new Managed Public Sessions feature so that Chromebooks can more easily be set up as public kiosks. The new feature allows users to surf the web without requiring any sort of login, all the while providing Administrators the tools they need via a web-based management console.
Google points to examples of where this could be useful. For instance, a retail store could set up a kiosk so customers could order out-of-stock merchandise. They could also be used in the business center of a hotel. The uses are really quite endless.
Administrators can easily customize any Chrome device to be a public session device using the web-based management console. The features that you'll find in the console include the ability to set the default sites and apps a user sees at login, custom brand the homepage, block sites and apps that shouldn't be accessed, configure device inputs and outputs, and set timed log-out sessions. For security reasons, public session data is cleared on logout so the next user starts fresh.
