About JWT Tokens
JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims between two parties. They consist of three parts: Header (algorithm info), Payload (claims/data), and Signature (verification).
Privacy: Your token is decoded entirely in your browser. No data is sent to any server.
