HumanCaptcha generates a simple question which the user must answer using logical thought. HumanCaptcha is much more accessible than standard captchas (which many people find difficult to read or understand). Visually impaired people are much more likely to be able to use HumanCaptcha than a character-based one. ** Captchas ** Most captchas are based on the requirement to reproduce a number of randomly-generated characters (which are sometimes blurred, jiggled and/or on a fuzzy background). HumanCaptcha generates a simple question which the user must answer using logical thought. HumanCaptcha is much more accessible than standard captchas, which many people find difficult to read or understand. Visually impaired people are more likely to be able to use HumanCaptcha than a character-based one. CAPTCHAs are useful for improving security in a number of situations, for example: 1. Reducing Comment Spam in Blogs Most bloggers will have come across programs that submit spam comments, often with the aim of improving the search engine ranking of a website. By using a CAPTCHA, only humans can enter comments on your blog, and people do not need to sign up before they enter a comment. 2. Protecting Email Addresses From Scrapers Spammers crawl the web looking for e- mail addresses rendered in text. CAPTCHAs can hide your e-mail address from web scrapers, by requiring users to solve a CAPTCHA before revealing your e-mail. 3. Deterring Viruses, Worms and Spam CAPTCHAs may reduce the likelihood of e-mailed viruses, worms and spam, by only accepting an e-mail if it has been established that there is a human behind the sending computer. #### Credits Many thanks to: TH90 (https://wordpress.org/support/profile/th90) of MPW D&D for the Persian translation files (fa_IR).

J’en étais vraiment ravi jusqu’à ce que récemment, je me suis aperçus d’une faille de sécurité majeure dans la page“ santé du ste” de Wordpress : Une session PHP a été créée par un appel de fonction session_start(). Cela interfère avec l’API REST et les requêtes de boucle (loopback). La session devrait être fermée par session_write_close() avant d’effectuer toute requête HTTP. La désactivation de toutes extensions de mon site pour les réactiver une à une ont imparablement diagnostiqué Human Captcha comme responable de cette faiblesse.Je comprends fort bien la réponse du développeur joint par courriel,qui m’indique être trop occupé par des activités rémunératrices pour s’en occuper, sauf si j’accepte de financer ce développement. Moi, quand je suis trop occuper, ce n’est pas un financement qui pourra m’occuper moins !J”espère que les 400 utilisateurs de l’extension que nous sommes n’auront pas à en pâtir ! ![](https://secure.gravatar.com/avatar/2b31b20c21a10087cdd1bf35f34bc3f62c76853527378ddbce89f97d1488cc2a? s=60&d=retro&r=g) ### 󠀁[awesome captcha](https://wordpress.org/support/topic/awesome-captcha-2/)󠁿 [sachsongngu](https://profiles.wordpress.org/sachsongngu/) Novembre 28, 2022 I have tried google recaptcha but somehow my site was still being spam until I change to this human captcha, no more spam user, comment….etc….all gone. Thank you very much for this great plugin and its author. PS: I used this plugin over 4 years. After a long time using and now I come back to review. ))) ![](https://secure.gravatar.com/avatar/85af1c4fd5e2d4226daaf9e2ae13bd99a5b56126ee617bef2aa52d1091c467d6? s=60&d=retro&r=g) ### 󠀁[Really simple and with a little help from the developer just what I want](https://wordpress.org/support/topic/really-simple-and-with-a-little-help-from-the-developer-just-what-i-want/)󠁿 [terokankaanpera](https://profiles.wordpress.org/terokankaanpera/) Setembre 24, 2021 Extremely simple and effective plug-in to cut ALL spam comments. This is just what I wanted: simple questions in the language my content is to block bots from forms on my site. Had a bit of teething trouble when I took it up, the language has characters it didn’t support correctly in combination with numbers but in the end the developer resolved this very fast. Could do with a little more features but KISS. ![](https://secure.gravatar.com/avatar/391cc352052f791d6b29a6c8ea42efc55888bd70f86e395e5c08977e5ae2a6b8? s=60&d=retro&r=g) ### 󠀁[So creative!](https://wordpress.org/support/topic/so-creative/)󠁿 [WPOso](https://profiles.wordpress.org/wordpress-oso/) Març 13, 2020 Three thumbs up for ease of installation, plus a another thumb up for creativity. I installed this plugin on three sites that cater to people who like to think, so being able to customize questions that are a little thought-provoking is a real treat. So far, everything seems to be working OK. David W.

It does what it’s supposed to do and does it well. I like the simple options to control where it appears as well as make my own captcha questions. However, The settings for this plugin appear under the Plugins menu item in the admin rather than the typical Settings menu where most would appear. This is extremely abnormal and easy to forget. Worse though, it made it completely unusable for me since I run a multisite network that hides the Plugins menu item in the admin areas. It makes it impossible to reach this plugins settings. So, can’t use it because of this unusual functionality. ![](https://secure.gravatar.com/avatar/a70fa033ae218c0a4043a8fe21e9766cb4238ecd541285052c9cdcfbf0bee61e? s=60&d=retro&r=g) ### 󠀁[Great captcha for accessibility](https://wordpress.org/support/topic/great-captcha-for-accessibility/)󠁿 [devra](https://profiles.wordpress.org/devra/) Setembre 3, 2016 Easy to install and set up. The is a better captcha for a low vision person, because they don’t have to try to interpret a fuzzy image with numbers or letters. Great captcha for people using screen readers.
