SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Python backends often struggle to securely verify user identity across services. This Skill provides a ready-to-use approach to verify JWT tokens in Python/FastAPI against the Better Auth TypeScript auth server using JWKS, ensuring secure access control across services.

Core Features & Use Cases

  • JWT verification for FastAPI backends using JWKS from Better Auth.
  • ORM integration templates for SQLModel and SQLAlchemy to enforce per-user data isolation.
  • Protected routes & dependencies to streamline security across microservices and frontend-backend boundaries.

Quick Start

Configure BETTER_AUTH_URL, install dependencies, and run your FastAPI app to begin JWT verification against Better Auth.

FAQPage Schema
How do I verify JWT tokens from Better Auth in a Python FastAPI backend?

Verify JWT tokens in FastAPI by fetching public keys via JWKS from the Better Auth server. This Skill implements a JWKS-based verification flow and a reusable get_current_user dependency to enforce secure access control across your services.

What's the best way to enforce per-user data isolation in FastAPI after JWT verification?

Enforce per-user data isolation in FastAPI by integrating JWT verification with ORM templates. This Skill provides integration templates for SQLModel and SQLAlchemy to restrict database queries based on the authenticated user identity.

Can I use a Python backend with a separate TypeScript Better Auth server for authentication?

Yes, you can use a Python FastAPI backend with a separate TypeScript Better Auth server. The Skill validates JWT tokens issued by Better Auth using JWKS, ensuring secure frontend-backend and microservice architectures.

How does JWKS-based JWT verification work for protecting FastAPI routes?

JWKS-based JWT verification protects FastAPI routes by retrieving cryptographic public keys from your Better Auth URL to validate token signatures. The Skill provides protected routes and environment variable configuration to streamline this security process.

Do I need to configure environment variables to start verifying JWTs against Better Auth?

Yes, you need to configure the BETTER_AUTH_URL environment variable to point to your Better Auth server. After setting this and installing dependencies, your FastAPI app can immediately begin validating JWT tokens.

Why does my FastAPI backend struggle to securely verify user identity across microservices?

FastAPI backends struggle to verify identity across microservices when lacking a standardized token validation method. This Skill solves the problem by implementing a JWKS-based verification flow against the Better Auth server, ensuring secure cross-service access control.
