Previously, we learned how to create a simple REST API in PHP. The create, read, update and delete database records (CRUD operations) has been useful for our projects.

Today, we will learn how to authenticate a user using REST API and JSON Web Tokens or JWT.

In this tutorial, we will cover a basic login, and create JWT Token and protecting resource using JWT.

In technical terms, JSON Web Token or 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 information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA.

JWTs are commonly used for organizations that have multiple applications or domains. Their users need to be authenticated (log in) once and be authorized to access multiple applications, domains, or resources of that organization.
JWTs are also used for an application that uses multiple servers.
In a single-server application, users can be authorized by session ID. A server will need to find (by lookup) a valid session ID on every HTTP request. Session IDs are stored on the server.
If your application needs to scale and needs multiple servers, you cannot use session IDs for user authorization. Every HTTP request will be routed to a different server where the session ID does not exist. Users will be logged out unexpectedly.
JWT helps solve the multi-server authorization problem by storing the authorized user information on the client-side, not on the server. JWT is sent on every HTTP request and it can be validated (by code) of any server used by the application.
