Learn more about Incognito and Guest mode
Note: At this time, Guest mode is only available on some versions of Chrome.
Both Incognito mode and Guest mode are temporary browsing modes, but there are some basic differences between them.
Incognito mode: You don't leave browsing history and cookies on your computer, but you can still see your existing history, bookmarks, passwords, Autofill data, and other Chrome settings.
Guest mode: A user in Guest mode does not leave any browsing history or cookies on the computer. In addition, they can't see or modify the computer owner's Chrome profile.
Important: Neither Incognito mode nor Guest mode makes you invisible on the web. Websites you visit, your employer, or your service provider can still see your browsing activity.
