WordPress powers millions of websites, making it a popular choice for bloggers, businesses, online publishers, and website owners. However, running a WordPress website also means taking responsibility for its security. Outdated plugins, weak passwords, poorly configured hosting, and unauthorized user accounts can create opportunities for security problems.
A reliable WordPress Security Checklist helps website owners identify common weaknesses and improve their website protection. Whether you manage a personal blog, business website, or content publishing platform, following basic security practices can reduce unnecessary risks.
Website security is not a one-time task. It requires regular updates, monitoring, backups, and careful management of website access. This guide covers 15 essential WordPress security checks, explains how to implement them, and provides a maintenance routine to help keep your website protected.
What Is a WordPress Security Checklist?
A WordPress Security Checklist is a collection of practical steps used to review and improve the security of a WordPress website.
It helps website owners check important areas such as software updates, administrator accounts, passwords, backups, hosting configurations, security monitoring, and website access permissions.
Instead of waiting for a security problem to occur, website owners can use a checklist to identify weaknesses before they cause significant damage.
A good security checklist should cover three main objectives:
- Prevention: Reduce opportunities for unauthorized access.
- Monitoring: Identify unusual activity and potential security problems.
- Recovery: Maintain reliable backups and a recovery plan.
Following these practices does not guarantee complete protection, but it can significantly improve your website’s security.
Why Is WordPress Website Security Important?
Website security affects more than just the ability to access your WordPress dashboard. A compromised website can experience several problems.
1. Unauthorized Website Access
Weak passwords and poorly managed administrator accounts can make unauthorized access more likely.
2. Data Loss
A website security incident, hosting failure, or accidental deletion can result in lost articles, images, settings, and database information.
3. Malware and Suspicious Files
Compromised plugins, themes, or other website components can introduce unwanted files and potentially harmful code.
4. Website Downtime
Security incidents can interrupt website availability and prevent visitors from accessing important information.
5. Search Engine Problems
A compromised website may display unwanted content, redirect visitors, or trigger browser security warnings. These problems can affect visitor confidence and search visibility.
For these reasons, website security should be part of regular WordPress maintenance.
15 Essential WordPress Security Checklist Steps
The following checks cover important security practices for both beginners and experienced WordPress administrators.
1. Keep WordPress Core Updated
Using an outdated WordPress version can leave your website exposed to vulnerabilities that have already been addressed in newer releases.
WordPress regularly provides updates that may include security improvements, bug fixes, and performance changes.
What to check:
- Open your WordPress dashboard.
- Navigate to Dashboard → Updates.
- Check the installed WordPress version.
- Install available updates after reviewing compatibility and backup status.
- Confirm that automatic security updates are working when enabled.
Keeping WordPress updated is one of the most important website security practices.
2. Update Plugins and Themes Regularly
Plugins and themes add useful features to WordPress, but outdated software can introduce security weaknesses.
Website owners should regularly review installed extensions and remove anything they no longer need.
What to check:
- Visit Plugins → Installed Plugins.
- Review available plugin updates.
- Update active plugins from trusted developers.
- Check Appearance → Themes for available updates.
- Remove unused plugins and themes.
- Avoid installing extensions from unknown websites.
Choose plugins and themes that receive regular maintenance and have reliable support.
3. Use Strong and Unique Passwords
Weak passwords make website accounts easier to compromise.
Every WordPress administrator should use a strong, unique password that is not reused on other websites.
Recommended practices:
- Use long passwords with a combination of characters.
- Avoid personal information and predictable words.
- Never share administrator passwords.
- Use a reputable password manager.
- Change passwords if unauthorized access is suspected.
A strong password is an essential part of protecting your WordPress dashboard.
4. Enable Two-Factor Authentication
Two-factor authentication (2FA) adds another verification step when someone signs in.
Instead of relying only on a password, users must provide an additional verification method.
Depending on the authentication system, this may involve an authenticator application, security key, or another supported method.
Enable 2FA for administrator accounts and other users who have important website permissions.
This additional layer can help protect accounts even if a password becomes exposed.
5. Limit Administrator Accounts
Not every person who works on a website needs administrator access.
WordPress provides different user roles that allow website owners to assign appropriate permissions.
| User role | Main purpose |
|---|---|
| Administrator | Full website management |
| Editor | Manage and publish content |
| Author | Publish and manage own posts |
| Contributor | Write posts for review |
| Subscriber | Manage basic profile information |
Security recommendations:
- Keep administrator accounts limited.
- Remove accounts that are no longer needed.
- Review user permissions regularly.
- Avoid sharing one administrator account.
- Assign the lowest suitable permission level.
This approach helps reduce the impact of unauthorized account access.
6. Install a Trusted WordPress Security Plugin
A reputable security plugin can help monitor website activity and identify potential security problems.
Depending on its features, a security plugin may provide:
- Malware scanning
- Login protection
- Firewall functionality
- Security notifications
- File change monitoring
- Suspicious activity detection
Choose a maintained plugin from a trusted developer and review its compatibility before installation.
Avoid installing multiple plugins that perform the same security functions because overlapping features can create unnecessary complexity.
Remember that a security plugin is only one part of a complete security strategy.
7. Enable HTTPS and SSL
HTTPS protects information exchanged between a visitor’s browser and your website through encrypted communication.
An SSL/TLS certificate is required to establish a secure HTTPS connection.
How to check:
- Open your website in a browser.
- Check whether the address starts with HTTPS.
- Confirm that the SSL certificate is valid.
- Configure your website to redirect HTTP requests to HTTPS.
- Check important pages for mixed-content warnings.
Many hosting providers offer SSL certificate options through their hosting control panels.
HTTPS is particularly important for websites that collect login information or other user-submitted data.
8. Create Regular Website Backups
Backups are essential because no website security system can eliminate every risk.
A reliable backup allows you to restore your website if files become damaged, information is deleted, or a security incident occurs.
Your backup should include:
- WordPress database
- Website files
- Uploaded images
- Themes and plugins
- Important configuration files
Recommended backup practices:
- Schedule automatic backups.
- Keep copies outside your hosting account.
- Maintain more than one backup version.
- Protect backup files from unauthorized access.
- Test the restoration process periodically.
A backup that has never been tested may not work when you actually need it.
9. Remove Unused WordPress Plugins and Themes
Inactive plugins and themes can still remain on your server.
Keeping unnecessary software installed increases the number of components you need to maintain.
Review your installed software and remove extensions that are no longer required.
Before deleting anything, confirm that your website does not depend on it.
For themes, keep your active theme and any necessary fallback theme while removing unnecessary alternatives.
A smaller collection of maintained components makes website management easier.
10. Disable the WordPress Dashboard File Editor
WordPress includes a built-in editor that can allow administrators to modify theme and plugin files through the dashboard.
If an unauthorized person gains administrator access, this feature could increase the potential damage.
Website owners who do not need dashboard-based code editing can disable it using the following setting in wp-config.php:
define( 'DISALLOW_FILE_EDIT', true );
Make a backup before changing configuration files and ensure the setting is added correctly.
This setting disables the built-in dashboard file editor. It does not replace other security protections or prevent every possible form of unauthorized file modification.
11. Protect WordPress Login Access
The WordPress login area is an important part of website security.
Automated login attempts and password guessing can create unnecessary risks.
Consider these practices:
- Use strong and unique login credentials.
- Enable two-factor authentication.
- Limit unnecessary administrator accounts.
- Use a reputable login protection feature.
- Monitor unusual login activity.
- Avoid sharing login details with others.
Do not rely only on changing the default login URL. Proper account protection is more important than hiding the login page.
12. Choose Secure WordPress Hosting
Website security also depends on the hosting environment.
A reliable hosting provider should maintain its server software, provide appropriate account isolation, and offer security-related features.
Before choosing or renewing hosting, review:
- Server software maintenance
- Supported PHP versions
- SSL certificate availability
- Backup options
- Firewall protection
- Malware detection
- Account security features
- Technical support availability
If you use shared hosting, ask your provider how accounts are isolated and what security protections are included.
Good hosting security complements the protection provided by WordPress itself.
13. Review WordPress File Permissions
File permissions determine which users and processes can read, modify, or execute files.
Incorrect permissions can create unnecessary security risks.
A commonly used starting point for standard WordPress installations is:
| File or directory | Common permission |
|---|---|
| Regular files | 644 |
| Directories | 755 |
| wp-config.php | More restrictive permissions, depending on hosting |
These are general reference values, not universal requirements. Actual permissions depend on your hosting configuration and file ownership.
Ask your hosting provider before changing permissions if you are unsure. Incorrect settings can prevent WordPress from working properly.
14. Monitor Website Activity and Security Alerts
Security monitoring helps website owners identify unusual changes and respond more quickly.
Pay attention to:
- Unexpected administrator accounts
- Unknown plugin installations
- Unusual file changes
- Suspicious login activity
- Unexpected website redirects
- Unfamiliar content or pages
- Security alerts from your hosting provider
Review your WordPress dashboard and available hosting logs regularly.
If something looks unfamiliar, investigate it instead of immediately assuming it is harmless.
15. Keep Your Website Software and Recovery Plan Organized
Security is an ongoing responsibility.
Website owners should maintain a regular routine for checking software updates, reviewing access permissions, testing backups, and monitoring security alerts.
Keep a record of important website settings and recovery procedures.
Also make sure that your hosting account, domain registrar, and website administrator accounts are protected with strong authentication.
An organized maintenance plan makes it easier to identify problems and restore normal website operation.

Common WordPress Security Mistakes to Avoid
Even website owners who follow basic security practices can make mistakes that weaken their protection.
Using Nulled Plugins and Themes
Modified premium themes and plugins from unauthorized sources may contain unwanted code or security problems.
Download software from WordPress.org or trusted developers.
Ignoring Available Updates
Delaying important security updates can leave known vulnerabilities unaddressed.
Check your dashboard regularly and confirm that updates have completed successfully.
Keeping Too Many Administrator Accounts
Unnecessary administrator accounts increase the number of accounts that require strong protection.
Review permissions and remove accounts that are no longer needed.
Relying Only on Security Plugins
A security plugin cannot replace regular backups, software updates, secure hosting, and responsible account management.
Use multiple security layers instead of depending on one tool.
Never Testing Backups
A backup is useful only when it can be restored successfully.
Periodically test your recovery process in a safe staging environment.
What to Do If Your WordPress Website Is Hacked
If you suspect that your website has been compromised, avoid making random changes that could destroy important evidence or backups.
Follow a careful recovery process:
- Contact your hosting provider and explain the suspected incident.
- Secure your hosting and WordPress administrator accounts.
- Change affected passwords using a trusted device.
- Enable two-factor authentication.
- Ask for a malware and suspicious-file investigation.
- Identify the source of the problem before restoring the website.
- Restore a known-clean backup if necessary.
- Update WordPress, plugins, and themes.
- Review administrator accounts and website permissions.
- Monitor the website after recovery.
If sensitive visitor information may have been exposed, follow applicable privacy and notification requirements.
A clean backup and professional hosting support can make the recovery process easier.
