pennersr/django-allauth is an excellent authentication package providing most of the required functionalities. It provided the following functionalities,

• Signup of both local and social accounts
• Connecting more than one social account to a local account
• Disconnecting a social account -- requires setting a password if only the local account remains
• Optional instant-signup for social accounts -- no questions asked
• E-mail address management (multiple e-mail addresses, setting a primary)
• Password forgotten flow

• E-mail address verification flow

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.
