title: Authenticate Using for webdriverjs
body: <p>How can you authenticate an authentication popup / alert with webdriverjs?</p>
  
  <p>This solution would need to work on Chrome, FF, IE8-11, iOS Safari, and Android.</p>
  
  <p>PhantomJS is not a consideration, so alerts are present.</p>
  
  <p>This solution can not use credentials in url, as Safari on iOS deems it a phishing attack, and it has been deprecated from the url spec.</p>
