You can change the database prefix during the WordPress installation process or by using a plugin like iThemes Security.

Limit Access to wp-admin Directory

Restrict access to the wp-admin directory by allowing only specific IP addresses to access it. You can achieve this by adding the following code to your .htaccess file:

<Files wp-login.php>
    order deny,allow
    Deny from all
    Allow from

Replace "" with your IP address. This prevents unauthorized users from accessing the WordPress admin area.

Educate Your Users

Security is not solely the responsibility of the website owner or administrator; all users should be aware of security best practices. Provide training to your team or contributors on how to recognize and avoid common security threats, such as phishing emails and suspicious links.

Regular Security Audits

Perform regular security audits of your WordPress website to identify and address potential vulnerabilities. You can use online security scanners or hire a professional security firm to conduct a comprehensive audit. Address any security issues promptly to ensure your website remains secure.
