How to Implement JWT Authentication with Next.js and WordPress CMS

Introduction

JWT (JSON Web Token) authentication is a popular way to authenticate users in web applications. It allows users to securely authenticate themselves without having to enter a username and password each time. In this article, we will show you how to implement JWT authentication with Next.js and WordPress CMS.

Requirements

In order to implement JWT authentication with Next.js and WordPress CMS, you will need the following:

  • A WordPress website with the WP REST API plugin installed and activated
  • A Next.js application
  • Node.js and npm installed

Step 1: Set Up the WordPress Website

The first step is to set up a WordPress website. You will need to install and activate the WP REST API plugin. This plugin allows you to access the WordPress data via an API.

Step 2: Install the JWT Authentication Plugin

The next step is to install the JWT Authentication plugin. This plugin allows you to authenticate users with JWT tokens. After installing and activating the plugin, you will need to configure it.

Step 3: Set Up the Next.js Application

The next step is to set up the Next.js application. You will need to install the next-auth and next-auth-jwt packages. These packages allow you to easily set up authentication with JWT tokens.

Step 4: Configure the JWT Authentication Plugin

The next step is to configure the JWT Authentication plugin. You will need to set the JWT secret and the JWT algorithm. You will also need to set the WordPress URL and the WordPress API endpoint.

Step 5: Implement the Authentication Flow

The final step is to implement the authentication flow. You will need to create a login page and a logout page. You will also need to create routes for handling the authentication requests.

Conclusion

In this article, we have shown you how to implement JWT authentication with Next.js and WordPress CMS. We have gone through the steps of setting up a WordPress website, installing the JWT Authentication plugin, setting up the Next.js application, configuring the plugin, and implementing the authentication flow. With this, you should now be able to securely authenticate users with JWT tokens.
