Authorization decides whether a particular user/service is allowed access to a particular route, service or resource. This is where JWT comes into the picture. It has a small overhead and it works across different domains. JWT Concepts 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. It’s one of the most popular ways of authentication. It’s an encoded string that can contain any amount of data and it is cryptographically signed (by the server side).
