What is a JWT?
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.
Note: We do not validate the signature here because we don't ask for your secret key. This tool merely decodes the base64url encoded parts.
