django-guardian is a Django object permission library that enables the assignment of fine-grained access rights to individual database records. This system provides object-level access control, allowing users or groups to be granted permissions for specific model instances rather than applying a single global rule to an entire data model. The library includes a permission manager for the Django administrative interface, which provides a visual dashboard to assign and audit these instance-specific security rules. It also features an anonymous access controller to define and verify permissions

Authlib is a comprehensive Python library for building and integrating OAuth 1.0, OAuth 2.0, and OpenID Connect clients and servers. It provides a unified set of tools to manage authentication and authorization flows, allowing applications to either act as a client connecting to external identity providers or as a provider issuing tokens and managing user identities. The project distinguishes itself through a full implementation of the JOSE standards, offering a suite of cryptographic tools for generating, signing, encrypting, and validating JSON Web Tokens, Signatures, Encryption, and Keys.
