    Question Google 2 step verification

    If you are trying to log in to your gmail account from a different computer, google will know it, and send you a SMS with a verification code...



    My question is, how does google know you are signing in from a different computer?
    I mean if you use the same IP address, it still knows. What else can it look? The MAC address of your network card?
    If you have the same MAC address and same IP address will it still know the difference?

    Just asking if you folks know. If not, then i'll try to find out.

    Maybe the computer name / browser / username / cookies / ..?

    Yes I just realized it is stored in cookies, and the cookies are stored different ways by different browsers :S.
    For example Firefox stores cookies in 1 sqlite file. IE stores all cookie in different file... etc.
