How to Secure WordPress: Best Practices for a Safe Website

WordPress is the world’s most popular content management system, powering over 40% of all websites. While its flexibility and ease of use make it a favorite, its popularity also makes it a prime target for hackers. The good news? By putting WordPress security best practices into action, you can keep your site safe from most threats and give yourself true peace of mind.

In this guide, you’ll learn practical, up-to-date steps to protect your WordPress site—no matter your technical background. Let’s get started.

Why Is WordPress Security Important?

Security isn’t just about avoiding headaches. A hacked site can mean:

  • Loss of sensitive customer data.
  • Reputation damage.
  • Downtime that affects sales and search rankings.
  • Possible blacklisting by Google, making your site hard to find.

Taking security seriously protects your investment, reputation, and your visitors’ trust.

Core Principles of WordPress Security

Before diving into specific steps, let’s set a strong foundation. The key principles of WordPress security are:

  1. Stay proactive, not reactive.
    Prevent issues before they happen, rather than fixing them afterward.

  2. Layer your security.
    Use multiple defenses—like strong passwords, updated software, and backups—so there’s no single point of failure.

  3. Stay informed.
    Keep up with common threats and update your approach as new risks emerge.

Essential WordPress Security Best Practices

1. Keep WordPress Updated

Updates are your first, easiest line of defense.

  • Always run the latest version of WordPress core.
  • Update plugins and themes as soon as new versions are available.
  • Look for plugins and themes that are regularly maintained.

Older versions often have vulnerabilities that are well-known in hacker communities. Updates contain not just new features, but crucial security patches.

2. Use Strong, Unique Passwords

Many breaches start with weak or reused passwords.

  • Create long passwords (12+ characters) mixing letters, numbers, and symbols.
  • Avoid using the same password for multiple sites.
  • Consider a password manager to keep track of your logins securely.

Also, never use “admin” as your username—choose something unique.

3. Limit Login Attempts

By default, WordPress allows unlimited login tries, making brute-force attacks easier.

  • Use a security plugin to limit login attempts.
  • Temporarily lock out users after several failed tries.
  • Enable features that notify you of repeated login failures.

4. Enable Two-Factor Authentication (2FA)

This adds an extra security step beyond your password.

  • After entering your password, you’ll also enter a code sent to your phone or generated by an app.
  • Even if your password is stolen, hackers can’t access your site without the second factor.

Many security plugins offer built-in 2FA features.

5. Install a Reliable Security Plugin

Security plugins make advanced protection easy for non-tech users:

  • Scan your site for malware and suspicious files.
  • Monitor login activity.
  • Harden core settings and provide firewalls.
  • Some popular options offer one-click fixes for common security holes.

6. Regular Backups Are a Must

Backups are your last line of defense if the worst happens.

  • Schedule automatic daily or weekly backups.
  • Store backups both locally and off-site (cloud storage or your own computer).
  • Test your backups regularly to ensure you can restore your site quickly.

7. Use Secure Hosting

Not all web hosts are created equal.

  • Choose a host with a proven track record in security.
  • Look for those that offer firewalls, malware scanning, and daily backups.
  • Managed WordPress hosts often include automatic updates and extra protection.

8. Secure Your Login and Admin Pages

Protect the “entrance” to your website:

  • Change your login URL from the default (/wp-login.php).
  • Limit admin access by IP address (where possible).
  • Disable user registration if not needed, or review new users manually.

9. Delete Unused Plugins and Themes

Inactive code can still be a gateway for hackers.

  • Remove (not just deactivate) plugins and themes you’re not using.
  • Review your list every few months.
  • Choose reputable plugins with positive reviews and ongoing support.

10. Use SSL (HTTPS) Across Your Site

SSL encrypts data moving between your site and visitors.

  • Most hosts provide a free SSL certificate.
  • Search engines favor secure sites, and users feel more confident.
  • Look for the padlock icon in browsers—this means your site is secure.

11. Set Proper File Permissions

Incorrect file permissions let attackers change important files.

  • WordPress folders should typically have permissions set to 755.
  • Files should be set to 644.
  • Some directories, like wp-config.php, can be set even more restrictively.

You can usually adjust permissions via your hosting control panel or FTP.

12. Disable File Editing in the Dashboard

By default, administrators can edit theme and plugin files in the WordPress dashboard. This is handy—but risky.

  • Add define( 'DISALLOW_FILE_EDIT', true ); to your wp-config.php file.
  • This stops hackers from using your dashboard to add malicious code.

13. Harden wp-config.php

This file contains your database credentials and site settings.

  • Move wp-config.php one level above your WordPress root directory if your host allows it.
  • Restrict access using .htaccess rules.
  • Monitor for unauthorized changes.

14. Watch Out for Third-Party Themes and Plugins

Not all plugins and themes are safe.

  • Stick with items from the official WordPress repository or trusted developers.
  • Avoid “nulled” or pirated items—these are often loaded with malware.

15. Set Up Web Application Firewalls (WAF)

A WAF blocks malicious traffic before it reaches WordPress.

  • Some hosts offer WAFs by default, or you can use dedicated plugins.
  • WAFs add an extra protective layer, screening out known exploits and attacks.

16. Regularly Scan for Malware

Attackers are always finding new tricks.

  • Use your security plugin to run periodic scans.
  • Look for unexpected files, database changes, or suspicious admin users.
  • Some tools can automatically remove malware or notify you if manual action is needed.

17. Disable XML-RPC When Not Needed

XML-RPC is a WordPress feature for remote publishing, but it’s often targeted for attacks.

  • Many sites do not require it—disable it unless needed.
  • Some security plugins allow you to turn it off with a click.

18. Hide WordPress Version Information

Exposing your WordPress version in your site’s code makes it easier for attackers to target you with known exploits.

  • Some security plugins can remove version numbers from your site’s HTML output.

19. Log and Monitor User Activity

If others have access to your site, keep an eye on what they do.

  • Use audit log plugins to track changes.
  • Set up alerts for suspicious activity, like multiple failed logins or changes to key files.

Advantages of Following Security Best Practices

By implementing these steps, you gain these benefits:

  • Drastically lower risk of hacking and data breaches.
  • Faster recovery in case of problems.
  • Improved search engine ranking and credibility.
  • Peace of mind for you and your site visitors.

Typical Challenges

Securing WordPress can seem complex, especially if you’re new. Here are common challenges:

  • Knowing which security settings matter most.
  • Keeping updates consistent.
  • Training other users or contributors to practice good password hygiene.
  • Balancing convenience with strong security (like 2FA and limited editing rights).

The solution? Start with the basics, and add layers as you grow more comfortable.

Budget-Friendly Security Tips

Not every solution requires a big budget! Here are some cost-effective tactics:

  • Use free versions of reputable security plugins—they offer solid basic protection.
  • Take advantage of free SSL certificates from your web host.
  • Store backups on free cloud platforms or your own devices.
  • Implement manual security hardening (like disabling file editing) with simple code tweaks.

For larger or business-critical sites, investing in premium plugins or managed hosting pays off in advanced features and time saved.

Summary

Securing your WordPress site doesn’t require you to be a tech expert or spend a fortune. The key is to take consistent, proactive steps:

  • Keep your software up to date.
  • Use strong passwords and extra authentication.
  • Back up your site regularly.
  • Install a robust security plugin.
  • Choose secure, dependable hosting.

By following these best practices, you’ll drastically reduce your site’s vulnerability and ensure a safer experience for everyone. Prioritizing security is investing in your website’s future success.
