JWT Authentication

JSON Web Tokens (JWT) provide a secure way to transmit claims between parties. They’re particularly useful in microservices architectures where you need to pass authentication and authorization information between services. JWTs are self-contained tokens that can include user information, permissions, and other claims.

How JWT Auth Works

1. Client authenticates and receives a JWT
2. JWT is included in subsequent requests (usually in Authorization header)
3. Server validates the JWT signature and claims
4. If valid, the request is processed with the claims’ context
