SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyjwt, cryptography, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill enables secure, scalable authentication between a Next.js frontend and a FastAPI backend using JWT and JWKS. It covers token generation, verification, JWKS endpoint setup, key rotation, and environment configuration for shared secrets.

Core Features & Use Cases

JWT generation & verification: Secure tokens between frontend and backend.
JWKS endpoint setup: Public key distribution and verification support.
Token rotation & security: Key rotation, expirations, and robust error handling.
Frontend-Backend integration: Stateless authentication with user isolation.

Quick Start

Configure the frontend to generate JWTs and call the JWKS endpoint.
Implement FastAPI middleware/dependency that verifies JWTs via JWKS.
Protect routes and enforce user isolation with proper error handling.
