title: Cookies used in Google login
body: <p>The first time I go to log in to Gmail (or another Google service), Google asks me to enter my Gmail address and password. The next time I go to log in, Google already knows my account and only asks for a password. Is there a cookie I can delete before going to the login page, so that Google ALWAYS asks me which account I want to log in to.</p>
  
  <p>This is for a web-app. I can run any JavaScript code, including deleting cookies and then redirect the browser to Google's login page.</p>
