About JWT Tokens
JWT (JSON Web Token) is a compact, self-contained way to transmit information between parties as a JSON object. It's commonly used for authentication and authorization in APIs.
A JWT consists of three parts separated by dots: header (algorithm info), payload (claims), and signature (verification). This tool decodes and displays all three parts for inspection.
