title: Password protection of part of Jekyll generated site
body: <p>I have a category that I want to protect using a password. I googled and found out some solutions to protect the whole site, but that's not what I want. I was wondering if there is a way to do that. Appreciate any suggestion.</p>
  
  <p>One of the scenarios is, the category, say called personal, is located in the navigation bar, when people click this button, they are asked to enter password to visit.</p>
