WordPress Security Best Practices

Securing Your WordPress Website

WordPress is secure by default, but following these best practices will help protect your site from common threats.

1. Keep Everything Updated

Regular updates are your first line of defense:

• Update WordPress core as soon as new versions are released
• Keep all plugins and themes up to date
• Remove unused plugins and themes
• Enable automatic updates for minor releases

2. Use Strong Passwords

Create complex passwords for:

• WordPress admin accounts
• Database users
• FTP/SFTP accounts
• Hosting control panel

Password requirements:

• Minimum 12 characters
• Mix of uppercase and lowercase letters
• Include numbers and special characters
• Use a password manager like LastPass or 1Password

3. Limit Login Attempts

Install a plugin like "Limit Login Attempts Reloaded" to:

• Block repeated failed login attempts
• Prevent brute force attacks
• Receive notifications of suspicious activity

4. Enable Two-Factor Authentication

Add an extra layer of security:

1. Install the "Two Factor Authentication" plugin
2. Configure with Google Authenticator or SMS

Modify these WordPress defaults:

8. Use SSL/HTTPS

Encrypt data transmission:

1. Install an SSL certificate (free with Let's Encrypt)
2. Force HTTPS in WordPress settings
3. Update all URLs to use https://
