A Chromebook is a laptop computer with a Chrome operating system. It is a lightweight, secure, and affordable way to get online and access apps, photos, documents, and more.
For some extra security on your Chromebook, you may want to disable guest browsing, which would prevent anyone with access to your Chromebook from using it without an account.
Guest browsing will now be disabled on your Chromebook, and anyone who tries to use your Chromebook will first need to sign in with their own account.
