Implement Secure Microservice Authentication with JWT Rotation

jwt microservices security authentication
Prompt
Design a robust JWT authentication middleware for a distributed microservices architecture using Node.js. Create a solution that implements automatic token rotation, supports refresh tokens with cryptographically secure random generation, and handles graceful token expiration across multiple service endpoints. Include error handling for token validation, implement a centralized token blacklist mechanism, and provide a mechanism for handling concurrent authentication requests with minimal performance overhead.
