sails‑permissions is a plug‑in for **sails.js** that adds a full‑featured authentication and authorization layer. It integrates with **passport.js** for login, provides role‑based access control, object ownership checks and row‑level security, and includes generators and policies to bootstrap an admin user and protect API endpoints—making it ideal for developers building Sails/Waterline applications that need a ready‑made permissions system.
