Application Passwords


In this article we are going to see all about the WordPress plugin Application Passwords.

Create different applications with unique passwords for any user to manage the REST API & XML requests.

Table of Content

Overview Overview

In simple basic authentication REST API & XML-RPC request we use the username and the password of the WordPress user.

Application Passwords provide a way to create multiple applications for each user to perform REST API authenticate requests without using users’ original passwords.

We have another plugin JSON Basic Authentication which allows us to perform basic authentication requests.
But JSON Basic Authentication uses the actual user password which is basically not useful for the live site.
Read more about performing basic authentication requests with JSON basic authentication plugin.

NOTE: Application Passwords is a Beta plugin in WordPress. So, I recommend avoiding using it on production sites. See all beta plugins in WordPress.

Examples of Application Passwords Examples of Application Passwords

Lets see how to use the Application Passwords with practical examples.

Here, I’m using Postman, CURL & wp_remote_post to demonstrate how we can create a new post with a Rest API request.

Create a post with Postman Create a post with Postman

  • Open Postman
Open a postman tool for testing Rest API requests.
Open Postman
  • Select GET method
  • Use your website URL
  • Click on Send

You will see something like:

Postman showing all the posts from the Rest API endpoint.
Get All Posts

Here, We have not used Application Password anywhere. We have just got the list of all posts to check the Rest API is enabled or not on our website.

Most of the times Rest API is disabled by security plugins. So, you can enable the Rest API support form them.

We have now created a application passwords. So we can use it to send the Basic authentication request.

In this example we are going to create a new post with Basic authentication.

To create the post we can need to use endpoint

In this example i’m just using only the title field to create a new post title.

You can see all available fields at –

Lets see how to do it.

  • Set the POST method
  • Add endpoint with title parameter and add post title like – /wp-json/wp/v2/posts/?title=Rest API Post 1
  • Select Authentication type Basic auth
  • Add your username
  • Add your application password

Note: Here the username is which you use to login to your website. And application password is newly created application password. Im my case it is mK7M wZmN Fuj5 IKYF XUAv EZ8H.

  • Click on Send button.

you can see something like

Create a new post Rest API request with the Postman.
Create a New Post Request

Now open your draft posts list. You can see our newly created post there.

Common Error & Solution Common Error & Solution

If somehow your server have not added the HTTP Authentication support then you can see something below error:

Due to a potential server misconfiguration, it seems that HTTP Basic Authorization may not work for the REST API on this site: Authorization headers are not being sent to WordPress by the webserver. You can learn more about this problem, and a possible solution, on our GitHub Wiki.


We need to add it from yourself into the .htaccess file. Add below code into your

RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]

After adding above code into .htaccess file we can use any application passwords.
