django-allauth is a reusable Django app that allows for both local and social authentication, with flows that just work.

Details

• Supports multiple authentication schemes (e.g. login by user name, or by e-mail), as well as multiple strategies for account verification (ranging from none to e-mail verification).
• All access tokens are consistently stored so that you can publish wall updates etc.
• Pluggable signup form for asking additional questions during signup.
• Support for connecting multiple social accounts to a Django user account.
• The required consumer keys and secrets for interacting with Facebook, Twitter and the likes are to be configured in the database via the Django admin using the SocialApp model.
• Consumer keys, tokens make use of the Django sites framework. This is especially helpful for larger multi-domain projects, but also allows for for easy switching between a development (localhost) and production setup without messing with your settings and database.
