What is a JSON Web Token (JWT)?

A 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. This information can be verified and trusted because it is digitally signed. JWTs are overwhelmingly used for stateless authentication and authorization in modern web and mobile applications.

A standard JWT consists of three parts separated by dots: a Header, a Payload, and a Signature. This tool allows you to safely decode the Base64Url encoded Header and Payload directly in your browser. Because it operates 100% client-side, your sensitive authentication tokens are never sent to a third-party server.
