Talk at Pycon India 2011 by Kiran Jonnalgadda. Summary : Managing user accounts is a pain. Standard methods like validating email addresses and resetting forgotten passwords are required for every app. Most large frameworks come with user management code, but if you run multiple websites and want to share users between them, you are on your own. LastUser is federated user management app. It runs standalone and supports authentication via OAuth2 using a protocol inspired by Twitter and Facebook. It can be plugged into your apps with minimal effort. LastUser is open source and available under the BSD license. LastUser supports Twitter and Google authentication and will seamlessly integrate with your app. We've so far built a client library for Flask that brings user management down to 10-15 lines of boilerplate code. Client libraries for other frameworks and languages are forthcoming.
