## Description

JustAuth is an OAuth 2.0 authentication library designed to integrate multiple third-party login providers into a single interface. It abstracts various social login APIs and identity services, allowing applications to manage authentication using the OAuth 2.0 and OIDC protocols.

The project provides a multi-provider identity integrator that replaces the need for individual vendor software development kits. It includes a toolkit for defining custom authentication platforms and proprietary identity services by specifying custom OAuth protocols and endpoints.

The library manages the full authentication workflow, from redirecting users to external providers to exchanging authorization codes for access tokens. It also includes a distributed session manager to cache authentication states and maintain security across multiple server instances using a shared caching layer.
