OmniAuth is a rack authentication framework that allows applications to verify user identities through third-party service providers using a single standardized interface. It functions as middleware to separate identity verification from core application logic by intercepting incoming requests. The project employs a strategy-pattern provider model to encapsulate provider-specific logic into interchangeable classes. It provides a custom authentication strategy framework and base classes for building new providers based on industry standards. The framework handles the multi-step authentication

Qor is a Go admin framework and backend toolkit used for building administrative interfaces, headless content management systems, and REST API generators. It provides a structured environment for implementing business application backends, specializing in the management of structured content and media assets. The project distinguishes itself through comprehensive multi-language content management, featuring locale-based data versioning and a dedicated system for internationalization and translation administration. It further differentiates its offering with a built-in state machine implementa

This project is an OAuth 2.0 client library and OpenID Connect SDK designed for integrating Microsoft identity platforms into JavaScript applications. It serves as a cross-platform authentication client for managing user identities and daemon services across browser-based and server-side environments. The library provides tools for acquiring and managing JSON Web Tokens to secure access to protected web APIs. It supports various authentication flows, including single-page application authentication, server-side identity management in Node.js, and non-interactive authentication for background

FastAPI Users is a ready-to-use authentication library for FastAPI applications that handles user registration, login, password reset, email verification, and profile retrieval with minimal configuration. It provides a complete authentication system built around pluggable backends and transports, supporting JWT tokens, database sessions, and Redis-based token storage that can be combined in a single route. The library distinguishes itself through its modular architecture, offering router-based module composition that organizes authentication flows as independent FastAPI routers for registrati

FastMCP is a Python framework designed for building servers that expose functions, resources, and prompts to AI models using the Model Context Protocol. It simplifies the development process by automatically deriving tool metadata, input schemas, and documentation directly from Python function signatures and type hints. The framework provides a unified container for managing these components, allowing developers to build modular applications that integrate seamlessly with AI assistants. The project distinguishes itself through its support for interactive, server-defined user interface compone

This is a Go library for obtaining, refreshing, and attaching OAuth 2.0 access tokens to HTTP requests. It provides a generic token source interface with interchangeable implementations for different OAuth 2.0 grant types, and wraps the Go net/http transport layer to automatically attach access tokens as Authorization headers on outgoing requests. The library supports the authorization code flow, generating consent page URLs and exchanging authorization codes for tokens. It also implements the device authorization grant for authentication on devices without a browser, and the resource owner p

Casbin is an authorization library designed to manage application access control and permissions through a configurable model-based engine. It serves as a centralized system for verifying whether a user has permission to perform specific actions on a resource. The engine supports multiple access control models, including Role-Based Access Control, Attribute-Based Access Control, and Access Control Lists. It allows for the definition of role hierarchies and the evaluation of user, resource, and environment attributes to make access decisions. The library decouples authorization logic from dat
