## Description

OpenAuth is a standards-based authentication server and identity provider that implements OAuth 2.0 and OpenID Connect protocols. It serves as a centralized system for managing user identities, issuing access tokens, and orchestrating authentication flows across various services.

The project functions as a federated identity gateway, aggregating external providers such as Google, GitHub, Microsoft, Apple, and Discord into a unified login flow. It distinguishes itself with a multi-tenant architecture that supports pluggable identity providers and customizable user interface frameworks for branding and theme management.

The platform covers comprehensive identity management, including local password authentication, email verification, and security PINs. It features a decoupled persistence layer with storage adapters for DynamoDB, key-value stores, and in-memory systems. Security capabilities include PKCE support, schema-based subject validation for identity payloads, and client access restrictions based on request metadata.

The software is designed for multi-environment deployment, allowing it to run as a standalone service or an embedded module across different cloud runtimes.
