With today’s Stable channel release, you can now add new users to Chrome. Adding new users lets you each have your own personal Chrome experience, and lets you each sign in to Chrome to sync your stuff. To add a new user to Chrome, go to Options (Preferences on a Mac), click “Personal Stuff,” and click “Add new user.” Check out our latest Beta blog post for a few quick tips.
Keep in mind that adding new users to Chrome isn’t intended to secure your data against other people using your computer, since it just takes a few clicks to switch between users. We’re providing this functionality as a quick and simple user interface convenience for people who are already sharing Chrome on the same computer today. To truly protect your data from being seen by others, please use the built-in user accounts on your operating system of choice.
