What Is Incognito Mode?
Incognito Mode in Chrome is Google's implementation of private browsing. Users can activate this mode and surf the internet without Chrome recording any cookies, usernames, passwords, or history.

Incognito Mode in Chrome is similar to Private Browsing in Firefox and InPrivate Browsing in Internet Explorer.
