Thread:Project:Support desk/How to use reCaptcha in Mediawiki

My current Mediawiki is version 1.20.2, and PHP & MySQL are latest versions. I have a question: how to prompt a user to enter reCaptcha when the user fails to register, login and submit an edited articles for a certain number of times?

The Mediawiki plugins mentioned in documents I found in Google are only for 1.17, which has not updated over 5 years, and it cannot be used in the latest version of Mediawiki. Is it possible to make reCaptcha internal in Mediawiki like PHPBB 3?
