How do I force a reCAPTCHA challenge?
- Use a VPN + incognito mode (as suggested here)
- If you're using the invisible reCAPTCHA, I found that using explicit rendering + immediately calling grecaptcha. execute() after grecaptcha. render() will usually trigger the challenge.
reCAPTCHA analyzes interactions with the website to detect if they are made by a human or some form of automated abuse. Sometimes, you may see a "failed reCAPTCHA check" error message while trying to create or amend your account. This means the website believes your actions may be those of a bot.
Use a VPN
VPN locations allow you to legitimately bypass Google's ReCAPTCHA roadblocks. For the best results, choose a well-known VPN service instead of a free VPN which would arrive with its own set of problems. Good VPNs disguise your traffic, protect your device details and don't record logs.
Invisible recaptcha check fails if you try to access your page via automated tests (in my case chrome browser) since chrome has a feature to recognize if the browsers is controlled by such software... so try to create easy tests in Python or Java(+webdriver), to see if recaptcha is implemented correctly.
Researchers Fool ReCAPTCHA With Google's Own Speech-To-Text Service. The new method has a 90 percent success rate at tricking the robot into thinking it's human.
- Automatically bind the challenge to a button or.
- Programmatically bind the challenge to a button or.
- Programmatically invoke the challenge.
In short, yes they can. While reCAPTCHA v2 and v3 can help limit simple bot traffic, both versions come with several problems: User experience suffers, as human users hate the image/audio recognition challenges. CAPTCHA farms and advances in AI allow cybercriminals and advanced bots to bypass reCAPTCHAs easily.
CAPTCHA has been around since the late 1990s, and by now, advanced bots are often able to bypass simple text and image-based CAPTCHAs. As a result, more advanced CAPTCHA now leverage behavior recognition and fingerprinting to maintain website security.
"Under the government's theory, anyone who disregards -- or doesn't read -- the terms of service on any website could face computer crime charges," said EFF civil liberties director Jennifer Granick in a press release.
Rebooting your modem/router should help to resolve it. Please also clear the browser data and cache when rebooting your modem/router.
Why can't bots solve CAPTCHAs?
Google combines (or hashes) that key with the web address you're visiting, so you can't use a CAPTCHA from one website to bypass another. It further combines that with “fingerprints” from your browser, catching microscopic variations in your computer that a bot would struggle to replicate (such as CSS rules).
Note: reCAPTCHA tokens expire after two minutes. If you're protecting an action with reCAPTCHA, make sure to call execute when the user takes the action rather than on page load.
