Undoubtedly ezrCaptCaha gives you this possibility. But ezrCaptcha (like all captchas on the market) is designed to perform a check at the end of the process, say when sending an email, a comment or any action that only requires verification at the end of the process. However, it is less efficient if several checks are required during the same process. It can be tedious for users to have to type the characters that appear in the captcha every time they go from one step to another.
As an advantage ezr Captcha is fully ADA compliant.
But ezr Image Captcha is designed specifically to perform fast multiple checks in each step required. This is more efficient if several checks are required during the same process.
As an disadvantage ezr Image Captcha is not fully ADA compliant.
