FAQs
1. What is a ReCAPTCHA v2 site key and why is it important?
The ReCAPTCHA v2 site key is a public identifier used to load and configure ReCAPTCHA on a specific website. It is essential for integrating ReCAPTCHA into applications or for programmatically handling CAPTCHA challenges, as it links the CAPTCHA to the correct domain and configuration.
2. Why is it difficult to manually find a ReCAPTCHA v2 site key?
Many websites load ReCAPTCHA dynamically through JavaScript, making the site key hard to locate in the page source. It may only appear after specific user actions trigger the CAPTCHA, which complicates manual inspection using standard browser tools.
3. How does CapSolver help with ReCAPTCHA v2 detection?
CapSolver automatically detects ReCAPTCHA-related parameters, including the site key, directly in the browser. By using its extension and built-in CAPTCHA detector, users can retrieve all necessary configuration details in a structured JSON format without manually searching through scripts or network requests.
