To enable JWT Authentication either add a dependency on the helidon-microprofile bundle or add the following dependency to your project’s pom.xml (see Managing Dependencies).

        <dependency>
            <groupId>io.helidon.microprofile.jwt</groupId>
            <artifactId>helidon-microprofile-jwt-auth</artifactId>
        </dependency>

JSON Web Token (JWT) defines a compact and self-contained way for securely transmitting information between parties as a JSON object. With JWT Auth you can integrate security features such as single sign on into your Helidon MP applications.

The main configuration point for JWT Auth is a JAX-RS Application class. As this class is discovered using CDI, it must have a bean defining annotation.

Example of an application that enables JWT-Auth (with minimal required annotations):

@LoginConfig(authMethod = "MP-JWT")
@ApplicationScoped
public class ProtectedApplication extends Application{
}
