WordPress Security Best Practices

by

WordPress is one of the most popular website platforms in the world. Because of its popularity, WordPress websites can become targets for hackers, malware, spam, and other security threats.

The good news is that you can significantly improve your website security by following some basic WordPress security practices.

In this guide, we’ll cover the essential WordPress security best practices every website owner and developer should follow.

1. Keep WordPress Updated

Always keep your WordPress core, themes, and plugins updated.

Updates often include:

  • Security fixes
  • Bug fixes
  • Performance improvements
  • New features

Using outdated software can leave your website vulnerable to known security issues.

Tip: Before major updates, take a backup of your website.

2. Use Strong Passwords

Use a strong and unique password for:

  • WordPress administrator accounts
  • Hosting accounts
  • Database accounts
  • FTP/SFTP accounts

Avoid simple passwords such as:

admin123
password123
wordpress

Use a combination of uppercase letters, lowercase letters, numbers, and special characters.

3. Enable Two-Factor Authentication

Two-factor authentication (2FA) adds an additional layer of security to your WordPress login.

Instead of relying only on a password, users may also need to verify their identity using an authentication app or another method.

This helps protect your website even if a password is compromised.

4. Use Trusted Plugins and Themes

Only install plugins and themes from trusted sources.

Before installing a plugin, check:

  • Developer reputation
  • Last update
  • WordPress compatibility
  • Reviews
  • Active installations

Avoid using nulled or pirated WordPress themes and plugins. They may contain malicious code or backdoors.

5. Use HTTPS

Always use HTTPS on your WordPress website.

HTTPS encrypts communication between the user’s browser and your website.

Your website should use a valid SSL/TLS certificate and load through:

https://example.com

instead of:

http://example.com

6. Take Regular Backups

Backups are one of the most important parts of website security.

A backup allows you to restore your website if something goes wrong.

Back up:

  • WordPress files
  • Database
  • Media uploads
  • Important configuration files

Ideally, keep backups in a separate location from your hosting server.

7. Use a Security Plugin

A WordPress security plugin can help protect your website against common threats.

Security plugins can provide features such as:

  • Malware scanning
  • Login protection
  • Firewall
  • Brute-force protection
  • Security monitoring

Choose a reputable security plugin and configure it according to your website’s requirements.

8. Protect the WordPress Login

The WordPress login page is a common target for brute-force attacks.

You can improve login security by:

  • Using strong passwords
  • Enabling 2FA
  • Limiting login attempts
  • Removing unused administrator accounts
  • Monitoring suspicious login activity

Avoid using admin as your administrator username.

9. Remove Unused Plugins and Themes

Don’t keep unused plugins and themes installed on your website.

If you don’t need them, remove them.

Unused software can become a security risk if it is not regularly maintained or updated.

Keep only the plugins and themes that your website actually needs.

10. Use Proper WordPress File Permissions

Incorrect file permissions can create security problems.

Your hosting environment should use appropriate permissions for WordPress files and directories.

Avoid giving unnecessary write permissions to files and folders.

If you’re unsure about permissions, check with your hosting provider before changing them.

11. Protect Your WordPress Admin Account

Don’t give administrator access to every user.

WordPress provides different user roles such as:

  • Administrator
  • Editor
  • Author
  • Contributor
  • Subscriber

Give users only the permissions they actually need.

This follows the principle of least privilege and reduces the risk of accidental or unauthorized changes.

12. Secure Your WordPress Development Code

If you’re developing custom WordPress themes or plugins, follow secure coding practices.

For example, escape output:

echo esc_html( $title );

Sanitize user input:

$name = sanitize_text_field( $_POST['name'] );

Use nonces when processing forms and sensitive actions:

wp_nonce_field( 'my_action', 'my_nonce' );

Never trust data submitted by users.

13. Use Secure Hosting

Choose a reliable WordPress hosting provider that provides security features such as:

  • SSL certificates
  • Firewalls
  • Malware monitoring
  • Regular backups
  • Server security
  • DDoS protection

Good hosting is an important part of WordPress security.

14. Monitor Your Website

Regularly check your website for unusual activity.

Look for:

  • Unknown administrator accounts
  • Unexpected files
  • Suspicious plugins
  • Unauthorized changes
  • Strange redirects
  • Unusual login attempts

Early detection can help prevent a small security problem from becoming a major issue.

Basic WordPress Security Checklist

Before launching your website, check:

  • WordPress is updated
  • Plugins and themes are updated
  • Strong passwords are being used
  • Two-factor authentication is enabled
  • HTTPS is configured
  • Regular backups are available
  • Unused plugins are removed
  • Unused themes are removed
  • User permissions are properly configured
  • Security monitoring is enabled
  • Hosting security is configured

Final Thoughts

WordPress security doesn’t have to be complicated. Following a few basic practices can significantly reduce the risk of attacks and data loss.

Keep your WordPress installation updated, use strong passwords, enable two-factor authentication, maintain regular backups, use trusted plugins and themes, and monitor your website regularly.

For developers, secure coding practices such as sanitization, validation, escaping, and nonces are equally important.

A secure WordPress website is not a one-time task—it requires regular updates, monitoring, backups, and maintenance.
