fastapi-auth-jwt

What problem does it solve?

This Skill provides a unified approach to authenticating FastAPI applications using either locally issued JWTs or external SaaS providers (Clerk/Supabase/Auth0), simplifying token validation and access control.

Core Features & Use Cases

• Local JWT issuance and verification alongside SaaS provider support.
• Unified token validation across multiple providers for protected endpoints.
• Easy integration into FastAPI apps with reusable dependencies and provider configuration.
• Use Case: Build an API that supports both self-hosted login flows and external authentication without rewriting security logic.

Quick Start

Install required libraries and wire up the token validator in your FastAPI app, then protect an endpoint with the dependency that validates the current user.
