title: Form authentication in Google Apps
body: <p>I've been wondering if it's possible to build and application in Google AppEngine (GAE) and provide to users not only a login through the Google Accounts. I'd like to also offer my own authentication. Something like <a href="http://www.appdemostore.com/signin" rel="nofollow">http://www.appdemostore.com/signin</a> . This app is built on top of GAE and not only provides a Google Accounts method to authenticate its users. It has a form authentication and a form to create an account hosted by itself. So, my point is: How could i implement something similar. Is it possible authenticate through my own forms and user's accounts instead of only Google Accounts?</p>
