Hacked website is the worst nightmare for any webmaster as it can cause a lot of troubles like data loss, time, money, website traffic, even your hosting can block your account, and search engines can blacklist your site as well because of malware.

We are confident that this WordPress security checklist will help you minimize the chances of your website getting hacked. 

Let’s get started. 

Basic WordPress Security Checklist

WordPress is the most popular CMS, which makes it popular among the hacking community.

This is the reason; we highly recommend that you follow this WordPress security checklist which includes all necessary basic security measures for all WordPress websites to minimize the hacking risk. 

Keep the Core WordPress Software Up to Date 

It is one of the vital WordPress security best practices that you must keep the WordPress software updated and maintained regularly. 

The benefits of keeping the core WordPress updated are:

  • Reduced WordPress security issues 
  • Better compatibility
  • Access to new WordPress features
  • A bug-free healthy WordPress website
  • Having a faster WordPress experience

step- 1 WordPress security checklist- WordPress Updates

You can also enable the auto-updates by using the WP-Config file by simply adding a single line i-e:-

define('WP_AUTO_UPDATE_CORE', true);

Pro Tip

Although you can set the updates automatically, we highly recommend keeping an eye on the updates regularly to fix the missed auto-updates or any conflicts after the auto-updates.

Just by having the latest version of WordPress core you can reduce the chances of hacking significantly.

Keep the Plugins & Themes Up to Date

WordPress plugins and themes allow you to enhance the functionality of your WordPress website.

Themes and plugin updates arrive when developers add new features or make a few tweaks and mostly when the updates are because of bugs and security vulnerabilities. Sometimes plugins/themes need to be updated to meet new WordPress version requirements. 

The benefits of keeping all the plugins and themes updated are:

  • Increased WordPress security
  • Repair of bugs
  • New features and functionalities
  • Having a better website performance

Your WordPress dashboard notifies you whenever there are any updates. 

The first indication is there will be a number against the update icon on the admin toolbar.

step - 2 WordPress security checklist- check notification in the WordPress dashboard

Moreover from updates, you can see how many plugins or which theme of your website needs to be updated, and for more details redirect to the plugin or theme tab respectively.

step - 3 WordPress security checklist - keep WP core, themes & plugins updated

You can also enable the auto-updates using the theme’s functions.php file or a site-specific plugin by merely adding a single line i-e:-

add_filter( 'auto_update_theme', '__return_true' );add_filter( 'auto_update_plugin', '__return_true' );

Please don’t add this code to the functions file if you are not familiar with coding. 

It’s better to take a quick overview of your complete website after updating the plugins and the themes and check the layout and all the functionalities like testing the forms, etc. 

Avoid Use Common User Names 

Here is the list of usernames to avoid while configuring your WordPress website:

  • adm/ admin/ admin1
  • host-name/manager
  • qwerty/root
  • support/sysadmin
  • test/user.

It’s essential to choose your user name carefully. Go for something unique, memorable, and avoid basing it on personal information that is easy to guess.

If you already have these admin user names, it is a good idea to replace them with some unique user names. 

There are two ways you can change your existing usernames:

  1. You can change the username manually by navigating on your WordPress dashboard.

Here you can add a new user or edit the previous one.

Step- 4 WordPress security checklist- update user names

  1. You can use a plugin to update the username like Easy Username Updater.

use Easy Username Updater to update the username

This method is simple and doesn’t involve creating a new account and you get to keep your email address.

It’s lightweight, well-reviewed, and straightforward to use. 

You can tweak its options under Users > Username Updater.

step 3 - WordPress security checklist- update usernames in WP

Don’t forget; it’s essential to pick a unique user name and secure credentials on your WordPress website.

Pro Tip

Try to use plugins as less as possible, or once you have used that plugin to update user names you can delete the plugin as it’s not something you need all the time.

Enforce Strong Password 

Your WordPress security is only as good as your WordPress password is.
If you have a simple password, it means you have a simple site to hack.

A few basics of WordPress password security are:

  • Include numbers, capitals, special characters (@, #, *, etc.)
  • Have a lengthy password (10 -50 characters)
  • Include spaces
  • Avoid using the same password in multiple places
  • Change passwords after every 1 or 2 months

Many plugins can help you to enforce strong WordPress Passwords for all users on your website like the iThemes Security plugin.

step 4- WordPress security checklist, enforce strong WordPress Passwords

It is easy to generate strong passwords from your WordPress admin dashboard.

Generate a strong user password

By utilizing the password protection features found in web hosting, WordPress, as well as plugins, you can quickly and easily add this extra layer of protection to any WordPress site.

Pro Tip

Sometimes it’s hard to remember these passwords so you can use tools like LastPass, Keeper, or 1Password tools which can help you to remember all your passwords over the cloud and can generate strong passwords as well.

Remove Inactive Themes & Plugins

Many WordPress users often install plugins or themes for testing and then deactivate them.

Inactive plugins and themes are harmful to your website security because they may:

  • Makes your website vulnerable to attacks
  • Deteriorate the performance of your website with time
  • Break any related functionality
  • Lead to WordPress security issues 

Delete all themes and plugins from your WordPress website, which are:

  • No longer in use
  • Outdated
  • Lead to security breaches

Before you do that make sure to take a fresh backup of your website because if something goes wrong, you can always revert to the previous version, without any risks. Follow this WordPress security checklist to remove inactive themes.

For removing inactive themes, navigate to our WordPress website dashboard.

Open Appearance > Themes and delete inactive themes.

step 6 - WordPress security checklist - delete extra theme from WP

For removing inactive plugins, navigate to our WordPress website dashboard.

Open Plugins > installed plugins and delete the inactive plugins, which you don’t need anymore.

installed plugins and delete the inactive plugins

Pro Tip

Each plugin you uninstall, leaves behind tables and rows in your website database. Over time, this can add a lot of data and even begin to slow down your site. So you should clean your database as well each plugin have its own options, or you may have to do it manually.

Ensure SSL Certificate Installed & HTTPs Option is Enforced

The idea of HTTPs has always been a good one. Most website owners implemented it a long time ago. Further, SSL certificates are now a requirement for all websites. This is the most important point of the WordPress security checklist.

The browsers like Google Chrome and Mozilla Firefox have mandated all sites to serve encryption via HTTPS. The browsers have created a new security warning if your website does not have an SSL certificate and missing https protocol to accomplish this transition. 

HTTPs make your site more secure for your users. More specifically, it’s safer when a user is giving you any sort of information. Most payment services, such as Authorize.net, PayPal IPN, etc. require an SSL to receive payments, to process the payment on your website. 

step 6 -WordPress security checklist get SSL certificate

HTTPs can provide multiple layers of protection. 

The benefits of having an HTTPs website provide you with many facilities like: 

  • Encryption
  • Data integrity
  • Authentication 
  • Security & Privacy
  • Boost up in SEO
  • Good Website Performance

Follow How to Install SSL Certificate on Your WordPress Website blog post and switch your website from HTTP to HTTPs.

Pro Tip

If you can get paid SSL that is good but if not you can always use Let’s Encrypt which now widely available and most host companies providing it as well within your hosting package as free. You can always check your SSL Certificate validity and working on https://sslchecker.com

Limited Admin Users

WordPress website has five types of users:

  • Administrator
  • Editor
  • Author
  • Contributor
  • Subscriber

The Administrator has the highest access level of the site users who can use all enabled site features.

That’s the reason why you should have to keep the limited admin users. In case, any admin user account is hacked, it will be terrible for your WordPress security.

You have three options to deal with extra admin user accounts to improve WordPress security:

Option 1: Delete All Unnecessary Admin User Accounts.

Delete all admin user accounts which are unnecessary and not in use.

Delete All Unnecessary Admin User Accounts

Option 2: Provide Limited Access to Admin Users

Here is the best option for them. Provide limited access to admin users. 
For example, You can create an admin user who can only update plugins and themes.

You can use the Controlled Admin Access plugin to do so.

Install the Controlled Admin Access plugin, activate it, and create a new admin user from your WordPress admin dashboard.

Option 3: Generate a Strong Admin User Password.

It’s better to change the password after every 1 or 2 months.

Open your WordPress admin dashboard.

Navigate to All users > Edit the user’s id and generate a new password.
