title: Ident/auth with temporary URLs in Pyramid
body: <p>I'm building a Pyramid application. In "normal" usage, users have to use typical username/password to login and do much of anything. The Pyramid documentation made it pretty easy to cut and paste and get that going.</p>
  
  <p>However, now I want to extend limited (both in authority and time -- permission expires on a given date) editing ability to people that I don't want to experience any account/password UI. I just want to email them a link that I generate, and when they click on the link I want them to land on the associated page and get identified and authorized to make some limited changes.</p>
  
  <p>All the obvious stuff like generating a link, storing it in the database, associating a username and expiration date, is no problem. It's plugging this into the Pyramid ident/auth framework that I don't know how to do. I made it this far without really understanding their code in depth, and am hoping that someone has a code example of what I want to do lying around that could allow me to continue to not dive into that topic.</p>
  
  <p>Or if the answer is stop being lazy and read the documentation, well, it cost me little to ask. :-)</p>
