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.
