Learn how JSON Web Tokens work and how to use them for an authentication system.
You will be able to understand what a JSON web token is through this short tutorial.
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 is done by digitally signing the JSON object so that the integrity of the content can be verified. It is often used to securely transmit information between front-end and back-end services.
