But now, the plugin installation forces you to pay, otherwise it doesn't protect your contact form. Using the open- source version is supposed to be possible… well… good luck to find how… ![](https://secure.gravatar.com/avatar/828be194b158eb9650a707521cfa24aab77b0c5c9962d1fed9fd3bc4d8b6f006? s=60&d=retro&r=g) ### 󠀁[ALTCHA free Version 1.26.3 = Excellent!](https://wordpress.org/support/topic/altcha-free-version-1-26-3-excellent/)󠁿 [nealumphred](https://profiles.wordpress.org/nealumphred/) 10 Tháng 5, 2026 The free version of ALTCHA (v. 1.26.3) is preposterously easy to set up, and then… it works just like it's supposed to! Excellent plugin, as is. ![](https://secure.gravatar.com/avatar/8ebc923f62bf4bc5c819c678bcd0f3e97beb55682b0da5498deaff72f2201f7f? s=60&d=retro&r=g) ### 󠀁[Works well](https://wordpress.org/support/topic/works-well-3123/)󠁿 [Hiroshi](https://profiles.wordpress.org/hiroshixo/) 24 Tháng 11, 2025 its a simple plugin easy to setup and work well with my websites… so far eliminated almost all spam +1 ![](https://secure.gravatar.com/avatar/2622b4c50ce5882f0c592046dacb4419fa52a26724f667037fb94f3d7b84da9a? s=60&d=retro&r=g) ### 󠀁[Thank you!](https://wordpress.org/support/topic/thank-you-3702/)󠁿 [abaantravis](https://profiles.wordpress.org/abaantravis/) 22 Tháng 11, 2025 I personally find this plugin very useful and working just fine, no problems. I don't understand why people here complain. Great work, thanks! And please keep this plugin alive. ![](https://secure.gravatar.com/avatar/68bc5a921734cd0c383fcfcd784bce2b8690ac51941fb73ca0f201ba96a66426? s=60&d=retro&r=g) ### 󠀁[Ruined by the devs](https://wordpress.org/support/topic/ruined-by-the-devs/)󠁿 [sarahsolus](https://profiles.wordpress.org/sarahsolus/) 17 Tháng 11, 2025 The version 1 Altcha WordPress plugin was a promising, if not perfect, captcha plugin. Unfortunately, the developers got everything wrong with version 2. First of all, it can only be installed via the website, which is suspicious. There are no upgrade notes, which is an absolute no-go for commercial sites. Incidentally, a captcha that installs itself into all forms without being asked is a very bad idea. For example, Altcha v2 also activates when using form-like elements such as filter widgets for lists. Or in globally integrated service forms, so that the Altcha screen pops up on every page. We also suspect that Altcha v2 prevents AI search engines from crawling – this has not yet been verified, but it coincides with the use of the plugin. For all these reasons, we have decided to stop using the plugin for the time being. ![](https://secure.gravatar.com/avatar/2a62c756e32000a959f02d3b7bbc2789af95fb13f543de0352df0a03cb734d03? s=60&d=retro&r=g) ### 󠀁[v1 was great; v2 – I had to uninstall](https://wordpress.org/support/topic/v1-was-great-v2-i-had-to-uninstall/)󠁿 [Alwyn Barry](https://profiles.wordpress.org/dramb/) 17 Tháng 11, 2025 Altcha v1 was brilliant – did just what I wanted seamlessly. Sadly when I installed v2 the login blocked for some users (and it was impossible to see why). I think the increased comms to the central system were to blame, but I'm not sure. I can't switch back to v1 without having the 'nag' to upgrade constantly visible on the plugin page, and putting the shortcode back into all the forms. A quick switch to Cloudfare Turnstile and all is working nicely. Sad, though, because Altcha looked great.
