title: How to build a secure Django single signon between different sites?
body: <p>I want to integrate my Django web application with other web based products (most likely 3rd party non-django applications.)  How can I let other sites sign in their users to my site with a single sign-on?  How would I store the usernames and passwords for the 3rd party sites users securely on my site to sign on my users to the 3rd part sites?</p>
