An extension to automatically solve any type hCaptcha

An extension to automatically solve any type hCaptcha. Supported: - hCaptcha How does it work. To get your API key you need to create an account on the solving service. Without API key extensions do not work. By completing hCaptcha on all websites, a browser addon assists users in solving difficult captchas. It is not guaranteed that the verification will always be solved. The technological limitations must be considered. Captcha difficulty can be so off-kilter that they appear friendlier to bots than to humans at times. The project's goal is to improve our experience with captchas by providing easy access to solutions already used by automated systems. hCaptcha challenges continue to be a significant burden on the web, delaying and frequently blocking access to services and information based on physical and cognitive abilities, social and cultural background, and the devices or networks from which they are connected.

No idea how it got 4.6 stars... every review, just like this one, is letting you know not to bother with this extension as its not free.

does not work and want you to pay

M M·15 Oct 2024

Does not work. They want you to pay for an ext. that probably does not work even if you did pay. Perhaps if there was some kind of a trial period to show that this does indeed work, I might consider paying for it. Do not install. Complete waste of time.👎
