title: Auto Login Chrome Extension
body: <p>I am working on a Chrome extension with a popup. This popup contains a login screen.</p>
  
  <p>I would like to add to this screen an autologin checkbox, so that the user doesn't have to type his password every time he closes his browser. I read that storing the password in the localStorage is not a good practice.</p>
  
  <p>Do you know what could be the best way to do so?</p>
  
  <p>For example, I am thinking of identifying the browser uniquely (something like a browser id), and storing it on my server. Does such an id exist?</p>
  
  <p>Otherwise, do you have any idea of how I can do it properly?</p>
  
  <p>Thank you!</p>
