Usage Guide

What is JWT?

JSON Web Token (JWT) is an open standard (RFC 7519) that transmits information between parties as a JSON object in a secure manner. The information can be verified and trusted because it is digitally signed. JWTs are commonly used for authentication and authorization, securely conveying user identity information between applications.
