title: Disable popup message in Magento 2.0
body: <p>I am designing my own theme in Magento for the first time (without any base theme).</p>
  
  <p>By default Magento loads a popup message that says "Checkout out as a new customer Creating an account has many benefits:...".</p>
  
  <p><strong>The question: How can I disable this message?</strong></p>
  
  <p>I know I can hide it using CSS, but I would like to remove it from the HTML code.</p>
  
  <p>Thanks!</p>
