awesome-lang-auth

An open source suite of embeddable authentication libraries that defines a single shared protocol implemented natively in multiple languages. Developers get production-grade authentication (password, OAuth 2.0, magic links, TOTP 2FA, RBAC, sessions, API keys) inside their own application, with any database, and the same API, security model and client libraries (Angular, React, Flutter, vanilla JS) whatever their stack. The Node.js reference implementation and the Python port are published on npm and PyPI and used in production; Go, Rust and Dart ports are in progress. The goal is a universal, plug-and-play auth standard: a versioned protocol specification, a language-independent conformance test suite, and aligned implementations across ecosystems.
