JWT authentication in Hono uses the `jose` library to issue and verify tokens statlessly across runtimes. Create login/signup endpoints that generate access tokens, apply auth middleware to extract and validate tokens, and attach verified user data to `c.var` for protected routes. This works on Node, Cloudflare Workers, and Vercel Edge.

Yes. Beyond access tokens, you can implement optional refresh tokens for extended sessions and cookie-based session management. Middleware verifies tokens, manages expiration, and rotates credentials while maintaining security across stateless and stateful patterns in your chosen runtime.

Role-based authorization uses helper middleware that checks user permissions attached to `c.var` after token verification. Define role or permission middleware, apply it to route groups or individual handlers, and enforce fine-grained access control without repeating auth logic across endpoints.

Yes. This Skill provides runtime-specific configuration handling for Node, Cloudflare Workers, and Vercel Edge, adjusting secret management and token lifetime handling to match each environment's constraints and capabilities.

Environment-driven secret management lets you configure API keys, signing secrets, and token expiration separately per deployment context. Load secrets from environment variables and adjust lifetimes in configuration, ensuring consistency and security without hardcoding credentials.

Auth middleware validates tokens and rejects expired or invalid credentials before they reach protected routes. Failed verification stops execution, prevents unauthorized access, and returns an error response, protecting your API from malformed or tampered tokens.
