Ever wondered about bypassing a Google reCaptcha using some captcha solver techniques? If yes, your next question must be how? Well, I have a quick solution that will help you bypass a Google reCaptcha using Node.Js. You can solve Google reCaptcha v2 and v3 both with the help of this tool.

I am using 2Captcha library to solve the reCaptcha. It is a Captcha Solving Software that bypasses the captcha within seconds.

Here is how to bypass captcha

The process of bypassing a captcha is mentioned below-

• Get the Captcha image from page in the form of data-sitekey parameter
• Transfer the parameter to 2captcha service
• The employee at 2captcha solves it
• Once it is solved, we get the response
• The response needs to set in the google reCaptcha textarea to make it work.

That’s it! Isn’t it easy? Yes its pretty easy to bypass. Let’s implement it in code.

Bypass Google Recaptcha using Node.Js

Here is step by step implementation of solving google recaptcha using Node.Js:

Setup Node.Js Application

You can skip this step if you have a existing Node.Js Application.

I am using Express Generator to generate a Node.Js boilerplate.

express bypass-captcha

Install 2captcha

Install the 2captcha package in Node.Js application.

npm install 2captcha

Get 2captcha API Key

The next step is to get a 2captcha API key. Create an Account at 2captcha. Confirm your account by clicking on the link sent to your mail. Go to Setting page to get your API key.

Integrate 2Captcha Code to bypass Google reCaptcha

Once everything is done, integrate the 2Captcha code.

const Captcha = require("2captcha")

// A new 'solver' instance with our API key
const solver = new Captcha.Solver("<Your 2captcha api key>")

/* Example ReCaptcha Website */
/*****
  @params
    - dataSiteKey
    - website url where captcha is placed
*****/
solver.recaptcha("6Ld2sf4SAAAAAKSgzs0Q13IZhY02Pyo31S2jgOB5", "https://patrickhlauke.github.io/recaptcha/")

.then((res) => {
    console.log(res)
})

Pass the API key in above code.

That’s it!! You have successfully bypass the Google v2/v3 reCaptcha. You can get more details about 2Captcha APIs here.
