title: How browser's identify login forms?
body: <p>I'm trying to find out: how browsers identify login forms in different sites?</p>
  
  <p>Doesn't matter if I'm acessing my GMail account or some personal project, IE/Firefox always knows that that page contains login info.</p>
  
  <p>Do they conclude that simply searching for input types = password or there is some cookie information involved?</p>
  
  <p>Thank you in advance.</p>
