What is a JWT?
A JSON Web Token (JWT) is a compact token used for authentication and exchanging data between services. It has three Base64URL-encoded parts separated by dots: header.payload.signature.
Security
This decoder is 100% local: your token is never sent to a server. Remember that a JWT is not encrypted — only encoded. Don't share tokens containing sensitive data.
