Decode/Encode JWT

What is a JWT?

A JSON Web Token (JWT) is a compact, URL-safe token format used for securely transmitting information between parties as a JSON object. JWTs are commonly used for authentication and authorization in web applications. They consist of three parts: a header, a payload, and a signature, separated by dots (e.g., header.payload.signature).
