Protecting OpenCart admin from brute force

For admin protection, I recommend a comprehensive approach:

1. Fail2ban for IP blocking

# /etc/fail2ban/jail.local
[opencart-admin]
enabled = true
filter = opencart-admin
logpath = /var/www/html/storage/logs/error.log
maxretry = 5
bantime = 3600

2. Two-Factor Authentication

Install Google Authenticator module from marketplace.

3. Captcha

// In login controller
if (!$this->captcha->verify()) {
    $this->error['captcha'] = 'Invalid captcha';
}

4. Additionally:

• Restrict access by IP via .htaccess
• Change admin path
• Use HTTPS
