title: Simple username & password protection of a bokeh server
body: <p>I have a simple bokeh server application and I want to expose it on a Linux-based Azure node. The server is there up and running. </p>
  
  <p>My question is: how to protect the content by username and password? I do not need necessarily authentication of users.</p>
  
  <p><strong>My ideas so far</strong> (not tried, may not work)</p>
  
  <ol>
  <li>To create an extra bokeh server page with a text field.</li>
  <li>On the callback for a button, to add the test if the password fits. If it does, to redirect to the original server page. Otherwise, inform the user about wrong credentials.</li>
  </ol>
