Add-On Type(s)



This extension changes the default graphics captchas into accessible (and more secure) question and answer pairs.

This extension changes the captchas from graphic words to user-definable questions and answers. The settings allow you to create up to 8 simple questions and answers (in the EE 1.x version) that will be randomly chosen in place of the captcha. These captchas are completely accessible as long as you remember to make the questions straightforward and without cultural context (unless you need to restrict usage to a specific group or type of site visitor).

The EE 2.x version allows any number of question and answer pairs and is also completely compatible with the Multi Site Manager. Each site can have its own independent set of Q&A pairs.

I’ve tried lots of add-ons to combat membership spam, none of them were as effective as this. Gone from 20 spam registrations per day to 0, 100% effective. Greg’s a great add-on developer too, highly recommended.

Outstanding.  Since I’ve installed this extension, my spam registrations have dropped from ten a day to zero, and improved my mood significantly.

Is VERY easy to install, works as expected. Good also: No difference between upper-/lowercase, so if your answer is “Greg” it will also accept “greg”.

Thanks, Greg!

Accessible Captcha is an excellent ad on that serves as a great alternative to the default captcha image. I’ve found it to be more reliable at blocking spam and junk posts than the traditional image, and the fact it’s a free add-on from Greg is fantastic. I’d highly recommend this add-on to others.

This is an indispensable extension for any kind of EE form. For reason’s passing understanding, EE doesn’t offer an accessible CAPTCHA by default. This extension is ridiculously easy to install and you’d be crazy not to use it on all your sites.
