WordPress, with its popularity, can be a target for brute force attacks, where malicious actors attempt to gain unauthorized access to your website by repeatedly guessing usernames and passwords. Protecting your WordPress site from such attacks is crucial for its security. In this guide, we’ll explore effective strategies to prevent WordPress brute force attacks, which will help enhance your website’s security.
Use Strong, Unique Passwords
The foundation of WordPress security begins with strong, unique passwords:
- Admin Passwords: Ensure that your admin, editor, and other user account passwords are complex and difficult to guess. Use a combination of uppercase and lowercase letters, numbers, and special characters.
- Password Manager: Consider using a reputable password manager to generate and store strong, unique passwords for each user. This ensures you don’t reuse passwords across accounts.
Limit Login Attempts
WordPress doesn’t have built-in login attempt limits, making it susceptible to brute force attacks. To address this:
- Use a Security Plugin: Install a security plugin like Limit Login Attempts Reloaded or Wordfence Security. These plugins allow you to set limits on login attempts and lock out users who exceed them.
- Adjust Settings: Configure the plugin to limit login attempts and specify the duration of lockouts. A common setting is to allow three to five login attempts before locking out an IP address for 15 minutes.
Implement Two-Factor Authentication (2FA)
2FA adds an extra layer of security by requiring users to provide two forms of verification before gaining access:
- Use a 2FA Plugin: Install a 2FA plugin like Google Authenticator – Two Factor Authentication (2FA) that supports 2FA. Once configured, users must enter a time-based code generated by the plugin.
- Enable Email or SMS 2FA: You can also enable email or SMS-based 2FA, where users receive a one-time code via email or text message that they must enter during login.
Rename the Login URL
By default, the WordPress login URL is “/wp-login.php,” making it a target for brute force attacks. Renaming it can add an extra layer of security:
- Use a Plugin: Install a security plugin that allows you to change the login URL. Popular plugins like WPS Hide Login can help you achieve this.
- Choose a Unique Login URL: Select a custom login URL that’s unique and not easily guessable. Avoid using common terms like “login” or “wp-login.”
Implement IP Whitelisting
IP whitelisting restricts access to the login page, allowing only specified IP addresses to access it:
- Configure Your Firewall: If your hosting provider offers firewall settings, configure it to allow only specific IP addresses to access your login page.
- Use a Security Plugin: Some security plugins allow you to set up IP whitelists for the login page. Ensure that you add your IP address to the whitelist.
Regularly Update WordPress and Plugins
Outdated WordPress versions and plugins can have vulnerabilities that attackers exploit:
- Automatic Updates: Enable automatic updates for WordPress core and plugins whenever possible. This ensures that you receive security patches promptly.
- Check for Updates Manually: Regularly check for updates and apply them as soon as they’re available. Outdated software is a common entry point for attackers.

Disable XML-RPC
XML-RPC is a protocol that can be abused by attackers in brute force attacks:
- Use a Plugin: Install a security plugin that allows you to disable XML-RPC. Plugins like Disable XML-RPC Pingback can help with this.
- Edit the .htaccess File: Advanced users can edit the website’s .htaccess file to disable XML-RPC by adding specific rules.
Monitor Login Activity
Stay informed about login activity on your website:
- Use Security Plugins: Security plugins often provide features to monitor login activity and send alerts for suspicious logins.
- Login Logs: Regularly review login logs to detect any unusual activity, such as repeated login failures from the same IP address.
Set Strong File Permissions
Ensure that file permissions on your server are correctly configured to prevent unauthorized access:
- Use the Principle of Least Privilege: Only grant necessary permissions to users. Limit write access to directories and files that require it.
- Regularly Audit Permissions: Periodically audit file and directory permissions to identify and rectify any vulnerabilities.
Backup Regularly
In case your site is compromised, having regular backups is essential:
- Automate Backups: Set up automated, off-site backups using a reliable backup plugin or your hosting provider’s backup service.
- Test Restores: Periodically test the restore process to ensure that your backups are functional.
