title: Pre-built login / authentication component for a php app?
body: <p>I know this question has been asked before, but I haven't found any answers that seem ideal.</p>
  
  <p>I have a php app that needs a login system.  I'm no crypto expert by any means, and I am wary of reinventing the wheel, which has doubtless been invented many times already, and very well.</p>
  
  <p>I'm wondering if anyone is aware of a good authentication component which can easily be integrated into an existing script, which adheres to all best practices and which, when combined with an ssl login, will satisfy all <em>reasonable</em> requirements for being secure.  </p>
  
  <p>I would prefer a stand-alone component, as opposed to having to setup an entire framework of some sort.  (The rest of the app does not use a framework, and I dislike the idea of having to use one, just for auth.)</p>
  
  <p>Thanks for your help,</p>
