Signing in with your social networking identity saves you from ever having to remember a username or password and allows a single click login. We only retrieve your email and name and use that to automatically generate an account here if you don't have one yet. If you're not already logged into your social networking account in this web browser they may prompt you to login, but Food Trucks Des Moines Iowa will not see your social networking password and will have no ability to change anything in your social networking account -- it's completely safe, and convenient.
