Ways to Harden Your WordPress Website

Now, we’ve landed on the real stuff of this blog. Some of the below-mentioned ways need coding or development experience, or else the mistakes caused due to ignoring this factor can lead to crashes and breakdowns.

Let’s begin with these hardening ways with at least some caution. Before that, keep in mind that you keep a backup of your website such that unnecessary complications can be avoided.

1. Install an SSL Certificate:

SSL or Secure Socket Layer Certificate moves your site from the HTTP version to the most secure HTTPS version. It ensures that all the data that’s stored on the server (user’s and website’s data) remains encrypted and safe.

Even Google prefers websites that have an SSL certificate on their website since it ensures the security of the users. Now, it penalizes the websites that show “Not Secure” in the browser instead of the green lock that appears beside HTTPS.

2. Use Strong Passwords:

This is one of the easiest and quickest ways of hardening your WordPress site. You need to make sure that all your administrators configure passwords that are at least 8 characters long. It must also include upper and lower case alphabets, numerals, and special characters.

Fortunately, WordPress offers a built-in secure password generator that can help you generate a difficult-to-guess password for your system administrators. Thus, if you notice that your password is easy-to-guess or isn’t secure, consider changing it and filling up this security loophole.

4. Use Two Factor Authentication:

The process of hardening your WordPress site isn’t over without protecting your site’s login from data thefts. Two-factor authentication is one of the ways of securing your WordPress site’s login page.

With this, visitors or users who’ll be trying to sign in to the account have to pass a 2 step process of verification, which includes:

  • Enter the correct username and password
  • Enter unique OTP sent to your device

5. Limit Login Attempts:

Do you why banks allow only three attempts to log in to their online portal? After the login attempts, you either get an option of ‘Forget Password’ or get logged out of your account. That’s an attempt to prevent forceful attacks from hackers.

By default, WordPress allows the users to attempt an unlimited number of login attempts which increases the chances of hacking. Thus, it is strongly advised that you limit the login attempts on your website such that hackers won’t be able to try many combinations to enter the site.

6. Disable File Editing:

WordPress offers a built-in code editor that allows us to edit the theme and files from the admin section. If it goes into the wrong hands, it can impose a security threat. Thus, it is recommended that you turn it off.

The process of disabling the file editor is simple and quick. You need to copy and paste the below-mentioned code into your wp-config.php file.

// Disallow file edit

define( 'DISALLOW_FILE_EDIT', true );

7. Secure the wp-config File:

The wp-config file contains information related to your site’s configuration. It is recommended that you protect the file from the attack of hackers by adding the below-mentioned code in the .htaccess file.

 <files wp-config.php>

order allow,deny

deny from all


8. Apply Password in your Admin & Login Page:

Generally, hackers can easily gain access to your admin folder and login page without any issues. This can allow them to apply their hacking strategies and get full access to your WordPress site.

To prevent this situation from occurring, you can add a password on the server-side level since it will help you block random requests from malicious IP addresses. This is one of the best ways of hardening your WordPress site.

9. Automatically Log out Idle Users: 

Most users who’re logged into a site sometimes wander away from their screen. This possess a great security threat to the site. Hackers can get into the admin section to make changes.

It is the main reason many financial institutions log out inactive users over time. This same functionality can be implemented on your WordPress site. For that, you need to install the Inactive Logout plugin on your site.

When it’s activated, visit Settings > Inactive Logout to make necessary changes to it. You can even set the time when it has to be logged out with a message. In the end, hit the save button to save this setting on your WordPress site.
