JWT Tips
- What is JWT? JSON Web Token (JWT) is a compact, URL-safe token format for secure data exchange.
- Structure: JWT consists of three parts: Header, Payload, and Signature, separated by dots (.).
- Use Cases: Authentication, Authorization, and Information Exchange.
- Security: Always use strong secrets and HTTPS to protect tokens.
- Expiry: Always set an expiration time (exp) to limit token validity.
