About JWT Tokens

What is JWT?

JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims to be transferred between two parties. They are commonly used for authentication and authorization in web applications.

JWT Structure:

  • • Header: Algorithm and token type
  • • Payload: Claims and data
  • • Signature: Verification data
  • • All parts are Base64URL encoded
