Protect your Opencart 2 store from brute force attacks by keeping track of login attempts and adding a captcha to the admin login page of your site.

1. Adds new table 'user_login' to record failed login attempts.
2. Locks account and requires captcha if incorrect login attempt reached.
   NOTE: captcha will only be shown if the 'Max Login Attempts' has been reached for the user. Set from store Settings default: 5

• Works with boths captchas:
  1. Basic Image
  2. Google
