A dug up line of code indicates Google's upcoming Chrome OS may have what is being called a Chrome OS login manager. While its significance can only be guessed at, it indicates that the Chrome web browser will be very closely integrated with the operating system. There is also speculation of the OS not allowing users to operate other web browsers on their machines. The login manager will be a single sign-on (SSO) cookie, eliminating the need for users to sign into their Google services, such as Gmail, Calendars, Docs, etc separately.
