Joomla 3.6.4, non-cloud standalone CAPTCHA plugin. Which one is better to install?

Question

Joomla

Hello.
Recommend a good CAPTCHA plugin that works standalone on the server and doesn't depend on other third party services.
It is necessary that it correctly gets into the system and works for user account forms: registration, recovery and login.
In advance, Thanks everyone!

What's wrong with standard reCAPTCHA?

Answer 2

Maybe look in the JED ?
By the way, you should definitely update Joomla :-) with a high probability your site has already been hacked.
