It would be justly to assert that the login page and user registration page become the victims of hackers’ attacks more often than any other pages. The internet villains try to get unauthorized access to the admin dashboard with a further possibility to insert malware, which could send emails to the users of your site, advertising the sites of their own or in some cases even make a total breach, by placing any infections into the WordPress core folder.
In case such interference does not concern the core files, the problem can be solved rather quickly, in other cases, when the core files are infected, it will take you a good time to make a profound cleaning and launch the site anew. This problem has been bothering the developers since the very appearance of the world web and the first precedents of hack. Previously the hackers worked with each site individually but in course of time, they have succeeded in the elaboration of automatic mechanisms, able to attack thousands of sites simultaneously. Quite often they can be attacked by the programs of usernames and passwords generation.
Just when the first cases of such programs’ activity were fixed, the necessity of any means creation, able to block them, increased substantially. The invention of Captcha became a preventive vaccine against possible diseases, able to get inside the vital organs of your site.
We would like to explain to you how the Captcha works and give a couple of tips on how to add this service to the WordPress login and registration form.
