title: Password protection, while keeping track of who is who
body: <p>I maintain a farmer market site. Part of the site includes a database with all of the different farmers and what they are harvesting this week.</p>
  
  <p>Currently I have one set of admin pages that are hidden from the public by the fact that I have not told anyone where they are at. With the admin pages I edit the data as needed. As more farmers get involved, it is getting to be a pain updating their data and I want to set it up so each farmer can signup, log on with their own password and edit what they have at market this week without me getting involved.</p>
  
  <p>I have seen plenty of scrips for password protecting a page. The ones that I have seen have been set up so that once a user is signed in they can view everything and there does not appear to be an easy way to keep track of who signed in.</p>
  
  <p>How do I build password protection, while keeping track of who is who, so that I can build the custom admin pages on the fly? Any tips or best practices to keep in mind?</p>
  
  <p>Thanks,</p>

  P.S. I have been using PHP and SQLite</p>
