How To Restrict Access To Wp-Admin In Nginx

Overview

Knowing how to secure your website is an important challenge that any website owner has to face. Especially in the case of WordPress websites, you have to make sure that your WordPress admin panel is secure and protected from unauthorized access. Nginx is a powerful web server which can help you protect your site’s admin pages. In this article, we will discuss how to restrict access to the wp-admin page for your WordPress site hosted on Nginx.

Configuring WordPress and Nginx Settings

The first step you need to take in order to restrict access to wp-admin for your Nginx-hosted WordPress website is to configure the settings in both WordPress and Nginx. In WordPress, you can configure access restrictions from your Dashboard. Go to Settings > General and scroll down till you find the Users section. Here, you’ll need to check the box next to any allowable user roles, such as Administrators and Editors. This will restrict any users who are not members of the allowed roles from accessing the wp-admin page.

Next, you will need to configure the Nginx settings. Open the Nginx configuration file and add the following code:


location = /wp-admin {
#Your IP range here
allow X.X.X.X;
deny all;
auth_basic "Administrator Login";
auth_basic_user_file /etc/nginx/.htpasswd;
}

This code will restrict access to the wp-admin page to only those in the allowed IP range. You can also restrict access to the wp-admin page by adding a username and password. To do this, you will need to use a tool like htpasswd to generate a .htpasswd file, which will contain the username and encrypted password. This will add an extra layer of security to prevent unauthorized access.

Customizing Nginx Rewrite Rules

If you want to customize the Nginx rewrite rules, then the following configuration can be used. This will redirect all requests to the wp-login.php page and return a 403 forbidden error instead of the actual login page.


rewrite ^/wp-admin/login.php$ /wp-admin/login-restricted.php break;

location = /wp-admin/login-restricted.php {
return 403;
}

Using HTTP Basic Auth

Another way to secure your wp-admin page is to use HTTP basic authentication. To do this, you first need to create a username and password file. Create a .htpasswd file in your Nginx directory and add the username and encrypted password. Then add the following code to your Nginx configuration file:


location = /wp-admin {
auth_basic "Administrator Login";
auth_basic_user_file /etc/nginx/.htpasswd;
}

This will ensure that all requests to the wp-admin page are authenticated using the username and password stored in the .htpasswd file.

Using OAuth

If you want an extra layer of security for your wp-admin page, then you can also use an authentication system based on OAuth. OAuth is an open standard for authorization that provides third-party access to user accounts, without sharing their passwords. Basically, it allows you to authenticate a user without needing their password. OAuth can be used to secure access to wp-admin pages by setting up an authorization request process.

To set up OAuth, you first need to register your website as an application with the provider. Once registered, you can then generate the necessary tokens and redirect URLs. You can then design a WordPress plugin that will let users authorize your application and thus grant access to the wp-admin page.

Conclusion

In this article, we discussed how to secure the wp-admin page on a Nginx-hosted WordPress site. We discussed how to set up access restrictions, configure Nginx settings, customize Nginx rewrite rules, secure access with HTTP basic authentication, and use OAuth for extra security. All of these techniques can be used in combination for an even more secure setup. With the right configuration, you can make sure that your wp-admin page is completely secure and protected from unauthorized access.
