title: CodeIgniter: lost password feature, how to implement?
body: <p>A client of mine has a site running on CodeIgniter (i did not create it, and know very little about CI), and they would like to add a lost password feature, and i have no idea how to approach implementing this feature using CI. I know PHP with most of my experience with it being from WordPress. </p>
  
  <p>Can someone point me in the right direction as to the best practices for implementing this kind of thing?</p>
