title: What google image can I use in my site for "Login with google"
body: <p>I am building a web application and I need it to have facebook and google authentication, but I can't find information about the use of google's policies for brand image use for this case.</p>
  
  <p>For facebook I found this:</p>
  
  <p><a href="https://www.facebook.com/brandpermissions/logos.php" rel="noreferrer">https://www.facebook.com/brandpermissions/logos.php</a></p>
  
  <p>but I can't find a similar page for google's brand image, all I found was this:</p>
  
  <p><a href="http://www.google.com/+/business/brand-guidelines.html" rel="noreferrer">http://www.google.com/+/business/brand-guidelines.html</a></p>
  
  <p>but they don't talk about login.</p>
  
  <p>Thank you very much in advace for your help</p>
