About JWT
JSON Web Tokens (JWT) are an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. A JWT consists of three parts: Header, Payload, and Signature, separated by dots. This tool decodes the Header and Payload locally in your browser — your token never leaves your device.
