JWT Guide

JSON Web Tokens (JWT) are an open standard for securely transmitting information between parties as a JSON object. A JWT consists of three parts separated by dots: the header (algorithm and type), the payload (claims), and the signature. They are widely used for authentication and authorization in APIs.
