WORDPRESS SECURITY: COMPLETE BEGINNER’S GUIDE TO PROTECTING YOUR WEBSITE
INTRODUCTION
WordPress powers over 43% of all websites on the internet. This popularity, while a testament to WordPress’s power and flexibility, also makes it an attractive target for hackers and cybercriminals.
Security might not be the most exciting topic for WordPress beginners, but it’s absolutely critical. A hacked website can result in data theft, malware distribution, damaged reputation, and significant financial loss.
The good news is that securing your WordPress website doesn’t require advanced technical knowledge. With the right strategies and tools, you can significantly reduce the risk of your website being compromised.
In this comprehensive guide, we’ll explore the most important WordPress security practices that every beginner should know. We’ll cover everything from strong passwords to regular backups, security plugins, and best practices for maintaining a secure website.
By implementing the strategies in this guide, you’ll have a much stronger defense against common WordPress attacks and threats.
Why WordPress Security Matters
Before diving into security strategies, let’s understand why WordPress security is so important for your website.
The Reality of WordPress Attacks
WordPress websites are targeted by hackers every single day. In fact, WordPress websites are hacked hundreds of thousands of times every year. The attacks range from simple attempts to guess admin passwords to sophisticated malware injections.
A hacked website can be devastating. Not only do hackers steal sensitive data, but they also:
Use your website to distribute malware to visitors
Send spam from your website
Deface your website content
Use your server resources to attack other websites
Damage your search engine rankings
Destroy your online reputation
The Cost of a Hacked Website
The financial impact of a hacked website can be severe. Beyond the direct cost of repairs, a compromised website can result in:
Lost customers and revenue
Legal liability if customer data is stolen
Higher hosting costs if resources are being abused
Significant time investment to recover
Potential blacklisting from search engines
Why Hackers Target WordPress
WordPress is targeted because:
It’s very popular (making it statistically likely)
It has a large ecosystem of plugins and themes (some with security vulnerabilities)
Beginners often use weak security practices
Outdated WordPress installations are common
Default usernames and weak passwords are frequently used
1. Keep WordPress Updated
The most important security practice is keeping WordPress, plugins, and themes updated.
Why Updates Matter
WordPress developers constantly discover and fix security vulnerabilities. When new versions are released, they often include critical security patches. Using outdated software means using software with known security vulnerabilities.
Updates not only fix security issues but also improve performance and add new features.
How to Update WordPress
- Go to Dashboard → Updates
- Click “Update Now” for WordPress core
- Update all plugins and themes
- Test your website after updates
Enable Automatic Updates
You can enable automatic updates in WordPress settings:
- Go to Dashboard → Settings → General
- Enable automatic updates for security releases
- Ensure your plugins and themes are also set to auto-update
Most hosting providers allow automatic updates, but some managed WordPress hosting providers handle this automatically.
2. Use Strong Passwords and Change Default Usernames
Weak passwords are one of the most common reasons WordPress websites get hacked. Many attacks begin with simple password guessing.
Password Requirements
A strong WordPress password should:
Be at least 12 characters long
Include uppercase and lowercase letters
Include numbers
Include special characters (!@#$%^&*)
Not contain dictionary words
Not contain your username or website name
Example Strong Password:
Secure#WordPress2026!PasswordChange Default Username
WordPress often comes with a default “admin” username. Hackers know this and target it specifically.
To change your admin username:
- Create a new administrator account with a strong username
- Assign all posts and pages to this new account
- Delete the old “admin” account
Many WordPress guides explain how to do this, and plugins can also help.
Use a Password Manager
Instead of trying to remember complex passwords, use a password manager like:
LastPass
1Password
Bitwarden
Dashlane
These tools generate and store complex passwords securely.
3. Use HTTPS and SSL Certificate
For a detailed step-by-step tutorial on setting up HTTPS, read our full guide on [How to Add SSL Certificate to WordPress on Hostinger].
HTTPS (Secure Socket Layer) encrypts data between your website and visitors. It’s now a standard security requirement.
Why HTTPS Matters
HTTPS encrypts sensitive information like login credentials and user data
Google gives ranking preference to HTTPS websites
Browsers show warnings for non-HTTPS websites
It protects user privacy
How to Enable HTTPS
Most hosting providers offer free SSL certificates through Let’s Encrypt.
Steps:
- Contact your hosting provider about SSL certificates
- Install the certificate (hosting provider usually does this)
- Update WordPress URL to use HTTPS:
- Dashboard → Settings → General
- Change “WordPress Address” and “Site Address” to https://
- Test your website
Most modern hosting providers automatically include free SSL certificates with hosting plans.
4. Install a WordPress Security Plugin
Security plugins provide ongoing protection and monitoring for your WordPress website.
Top WordPress Security Plugins
Wordfence: Comprehensive security plugin with firewall and malware scanning
Sucuri: Powerful security suite with monitoring and malware removal
iThemes Security: User-friendly security plugin with multiple protection layers
All In One WP Security: Free plugin with essential security features

Alert you to security issues
How to Set Up a Security Plugin
- Install your chosen security plugin from WordPress.org
- Activate the plugin
- Run initial setup (usually guided)
- Configure recommended settings
- Run security scan
- Enable real-time monitoring
5. Regular Backups Are Essential
Backups are your insurance policy against website disasters. If something goes wrong, backups allow you to restore your website.
Why Backups Matter
Backups protect against:
Hacking and malware
Server failures
Accidental data deletion
Plugin conflicts that break your site
Natural disasters
Backup Strategy
You should maintain:
Daily automated backups
Off-site backup storage (not just on your server)
Multiple backup copies
Regular backup testing (restore backups periodically to ensure they work)
WordPress Backup Plugins
UpdraftPlus: Easy automated backups with cloud storage options
BackWPup: Free backup plugin with scheduling
Duplicator: Backup and migration plugin
VaultPress: Automatic backups by Jetpack
How Often to Back Up
Daily backups are ideal for active websites
Weekly backups minimum for less active sites
More frequent backups for e-commerce or sites with sensitive data
6. Limit Login Attempts
Brute force attacks automatically try thousands of passwords to guess your login credentials. Limiting login attempts stops these attacks.
How to Limit Login Attempts
Most security plugins automatically do this, but you can also:
- Install a security plugin with login protection
- Configure the plugin to limit login attempts (usually 5 attempts per 15 minutes)
- Set lockout duration (usually 24 hours after max attempts)
- Enable login notifications
Additional Login Protection
Two-Factor Authentication (2FA): Requires an additional verification method
IP Whitelisting: Allow logins only from specific IP addresses
Login URL Change: Move login from the default /wp-admin/ location
7. Remove Unnecessary Plugins and Themes
Every plugin and theme is potential security risk. Unused plugins and themes can contain vulnerabilities.
Security Best Practices for Plugins
Only install plugins from official WordPress.org repository
Delete unused plugins immediately
Keep active plugins updated
Read plugin reviews and check author credibility
Use security plugins that scan for vulnerable plugins
Theme Security
Only use themes from reputable sources (official WordPress.org, premium marketplaces)
Delete unused themes
Keep your active theme updated
Avoid pirated themes from unreliable sources
Regular Cleanup
- Audit all installed plugins and themes quarterly
- Deactivate and delete anything you’re not using
- Keep only essential, regularly updated plugins
- Monitor for outdated or unsupported plugins
8. Disable File Editing and XML-RPC
WordPress has features that can be security risks if you’re not using them.
Disable File Editing
WordPress allows editing theme and plugin files through the dashboard. This is dangerous if your account is compromised.
To disable file editing, add this to your wp-config.php file:
define('DISALLOW_FILE_EDIT', true);This prevents anyone from editing files through the WordPress dashboard.
Disable XML-RPC
XML-RPC is a legacy feature that’s rarely used but can be exploited. Unless you specifically need it, disable it.
Most security plugins have an option to disable XML-RPC, or you can add this to your .htaccess file.
9. Monitor Your Website Regularly
Security is not set-and-forget. Regular monitoring helps catch problems early.
What to Monitor
Check your website daily for unusual behavior
Monitor security plugin alerts
Review website analytics for suspicious activity
Check your website files for unauthorized modifications
Monitor login attempts
Review user accounts for unauthorized accounts
Tools for Monitoring
Security plugins provide automated monitoring
Google Search Console alerts about issues
Website uptime monitoring services
Log file monitoring
Regular manual inspections
