WordPress REST API – Authentication Broker

Used together with the WP REST API OAuth 1.0a Server plugin, this allows the WP RET API Authentication Broker

tmeister

This plugin seamlessly extends the WP REST API, enabling robust and secure authentication using JSON Web Tokens (JWT). It provides a straightforward way to authenticate users via the REST API, returning a standard JWT upon successful login.
<h3>Key features of this free version include:</h3>
<ul>
<li>Standard JWT Authentication: Implements the industry-standard <a href="https://tools.ietf.org/html/rfc7519" rel="nofollow ugc">RFC 7519</a> for secure claims representation.</li>
<li>Simple Endpoints: Offers clear <code>/token</code> and <code>/token/validate</code> endpoints for generating and validating tokens.</li>
<li>Configurable Secret Key: Define your unique secret key via <code>wp-config.php</code> for secure token signing.</li>
<li>Optional CORS Support: Easily enable Cross-Origin Resource Sharing support via a <code>wp-config.php</code> constant.</li>
<li>Developer Hooks: Provides filters (<code>jwt_auth_expire</code>, <code>jwt_auth_token_before_sign</code>, etc.) for customizing token behavior.</li>
</ul>
JSON Web Tokens are an open, industry standard method for representing claims securely between two parties.
For users requiring more advanced capabilities such as multiple signing algorithms (RS256, ES256), token refresh/revocation, UI-based configuration, or priority support, consider checking out <a href="https://jwtauth.pro/?utm_source=wp_plugin_readme&utm_medium=link&utm_campaign=pro_promotion&utm_content=description_link_soft" rel="nofollow ugc">JWT Authentication PRO</a>.

<h3>REQUIREMENTS</h3>
<h4>WP REST API V2</h4>
This plugin was conceived to extend the <a href="https://github.com/WP-API/WP-API" rel="nofollow ugc">WP REST API V2</a> plugin features and, of course, was built on top of it.
So, to use the wp-api-jwt-auth you need to install and activate <a href="https://github.com/WP-API/WP-API" rel="nofollow ugc">WP REST API</a>.
<h3>PHP</h3>
Minimum PHP version: 7.4.0
<h3>PHP HTTP Authorization Header Enable</h3>
Most shared hosting providers have disabled the HTTP Authorization Header by default.
To enable this option you’ll need to edit your .htaccess file by adding the following:
<pre><code>RewriteEngine on
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]
</code></pre>
<h4>WPENGINE</h4>
For WPEngine hosting, you’ll need to edit your .htaccess file by adding the following:
<pre><code>SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
</code></pre>
See https://github.com/Tmeister/wp-api-jwt-auth/issues/1 for more details.
<h3>CONFIGURATION</h3>
<h3>Configure the Secret Key</h3>
The JWT needs a secret key to sign the token. This secret key must be unique and never revealed.
To add the secret key, edit your wp-config.php file and add a new constant called JWT_AUTH_SECRET_KEY:
<pre><code>define('JWT_AUTH_SECRET_KEY', 'your-top-secret-key');
</code></pre>
You can generate a secure key from: https://api.wordpress.org/secret-key/1.1/salt/
Looking for easier configuration? <a href="https://jwtauth.pro/?utm_source=wp_plugin_readme&utm_medium=link&utm_campaign=pro_promotion&utm_content=config_secret_key_link" rel="nofollow ugc">JWT Authentication PRO</a> allows you to manage all settings through a simple admin UI.
<h3>Configure CORS Support</h3>
The wp-api-jwt-auth plugin has the option to activate <a href="https://en.wikipedia.org/wiki/Cross-origin_resource_sharing" rel="nofollow ugc">CORS</a> support.
To enable CORS Support, edit your wp-config.php file and add a new constant called JWT_AUTH_CORS_ENABLE:
<pre><code>define('JWT_AUTH_CORS_ENABLE', true);
</code></pre>
Finally, activate the plugin within your wp-admin.
<h3>Namespace and Endpoints</h3>
When the plugin is activated, a new namespace is added:
<pre><code>/jwt-auth/v1
</code></pre>
Also, two new endpoints are added to this namespace:
Endpoint | HTTP Verb 
/wp-json/jwt-auth/v1/token | POST 
/wp-json/jwt-auth/v1/token/validate | POST
Need more functionality? <a href="https://jwtauth.pro/?utm_source=wp_plugin_readme&utm_medium=link&utm_campaign=pro_promotion&utm_content=endpoints_pro_note" rel="nofollow ugc">JWT Authentication PRO</a> includes additional endpoints for token refresh and revocation.
<h3>USAGE</h3>
<h4>/wp-json/jwt-auth/v1/token</h4>
This is the entry point for JWT Authentication.
It validates the user credentials, username and password, and returns a token to use in future requests to the API if the authentication is correct, or an error if authentication fails.
Sample Request Using AngularJS
<pre><code>(function() {
 var app = angular.module('jwtAuth', []);

 app.controller('MainController', function($scope, $http) {
 var apiHost = 'http://yourdomain.com/wp-json';

 $http.post(apiHost + '/jwt-auth/v1/token', {
 username: 'admin',
 password: 'password'
 })
 .then(function(response) {
 console.log(response.data)
 })
 .catch(function(error) {
 console.error('Error', error.data[0]);
 });
 });
})();
</code></pre>
Success Response From The Server
<pre><code>{
 "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOlwvXC9qd3QuZGV2IiwiaWF0IjoxNDM4NTcxMDUwLCJuYmYiOjE0Mzg1NzEwNTAsImV4cCI6MTQzOTE3NTg1MCwiZGF0YSI6eyJ1c2VyIjp7ImlkIjoiMSJ9fX0.YNe6AyWW4B7ZwfFE5wJ0O6qQ8QFcYizimDmBy6hCH_8",
 "user_display_name": "admin",
 "user_email": "admin@localhost.dev",
 "user_nicename": "admin"
}
</code></pre>
Error Response From The Server
<pre><code>{
 "code": "jwt_auth_failed",
 "data": {
 "status": 403
 },
 "message": "Invalid Credentials."
}
</code></pre>
Once you get the token, you must store it somewhere in your application, e.g., in a cookie or using localStorage.
From this point, you should pass this token with every API call.
Sample Call Using The Authorization Header With AngularJS
<pre><code>app.config(function($httpProvider) {
 $httpProvider.interceptors.push(['$q', '$location', '$cookies', function($q, $location, $cookies) {
 return {
 'request': function(config) {
 config.headers = config.headers || {};
 // Assume that you store the token in a cookie
 var globals = $cookies.getObject('globals') || {};
 // If the cookie has the CurrentUser and the token
 // add the Authorization header in each request
 if (globals.currentUser && globals.currentUser.token) {
 config.headers.Authorization = 'Bearer ' + globals.currentUser.token;
 }
 return config;
 }
 };
 }]);
});
</code></pre>
The wp-api-jwt-auth plugin will intercept every call to the server and will look for the Authorization Header. If the Authorization header is present, it will try to decode the token and will set the user according to the data stored in it.
If the token is valid, the API call flow will continue as normal.
Sample Headers
<pre><code>POST /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer mF_s9.B5f-4.1JqM
</code></pre>
<h3>ERRORS</h3>
If the token is invalid, an error will be returned. Here are some sample errors:
Invalid Credentials
<pre><code>[
 {
 "code": "jwt_auth_failed",
 "message": "Invalid Credentials.",
 "data": {
 "status": 403
 }
 }
]
</code></pre>
Invalid Signature
<pre><code>[
 {
 "code": "jwt_auth_invalid_token",
 "message": "Signature verification failed",
 "data": {
 "status": 403
 }
 }
]
</code></pre>
Expired Token
<pre><code>[
 {
 "code": "jwt_auth_invalid_token",
 "message": "Expired token",
 "data": {
 "status": 403
 }
 }
]
</code></pre>

<h4>/wp-json/jwt-auth/v1/token/validate</h4>
This is a simple helper endpoint to validate a token. You only need to make a POST request with the Authorization header.
Valid Token Response
<pre><code>{
 "code": "jwt_auth_valid_token",
 "data": {
 "status": 200
 }
}
</code></pre>

JWT Authentication for WP REST API

I was confused about choosing the jwt plugin. There are 3 versions, the first has not been updated for 6 months and the second has not been updated for two months, the first has not worked, the second has unclear instructions and has some defects despite the presence of a dashboard, and this add-on has not been updated for two years  But when I saw that it was updated a day ago, I decided to use it and all the problems that I was facing were resolved. I ask the add-on developers to update them every period, but there is something unclear, how can I amend the token expiry time?  Thanks

good


It breaks APIs that don't require authorization.



Such as WordPress's posts endpoint and WooCommerce's endpoint.

Perfect! This plugin is very easy to install and use. It's also easy to extend and add your own return data.


Easy to use and extend


I've been using the plugin for over year, it's very good and user friendly!



At some point there was a constant message to upgrade, but that was fixed.


Great plugin!
