title: Best practice about login
body: <p>I have made a decent website using HTML, CSS and JavaScript. I'm new to programming.</p>
  
  <p>Now I want to give some privacy to some users and create a login space. I saw that some people are using PHP, other JS or Node.js, but I haven't seen any good guide for the best practice.</p>
  
  <p>I would like to make a robust website with up-to-date technologies. What is the best practice for this kind of request?</p>
