Step-by-Step Guide to Determining reCaptcha Version

Now that we’ve covered the basics, let’s get down to business! Here’s a step-by-step guide to determining whether a website is using reCaptcha V3 or V2:

Step 1: Inspect the Website’s Source Code

The first step is to inspect the website’s source code. You can do this by right-clicking on the website and selecting “Inspect” or “Inspect Element” (the exact terminology may vary depending on your browser). This will open the developer console.

    
        // Press F12 or right-click and select "Inspect" to open the developer console
    

Step 2: Search for reCaptcha Scripts

In the developer console, switch to the “Elements” tab and press Ctrl + F (or Cmd + F on a Mac) to open the search bar. Type “recaptcha” in the search bar and press Enter. This will highlight any reCaptcha-related scripts on the webpage.

    
        // Search for reCaptcha scripts in the Elements tab
        // Type "recaptcha" in the search bar and press Enter
    

Step 3: Identify the reCaptcha Version

Once you’ve found the reCaptcha script, inspect the script tag. Look for the following patterns to determine the reCaptcha version:

• reCaptcha V2: The script tag will likely contain the following pattern: src="https://www.google.com/recaptcha/api.js">

• reCaptcha V3: The script tag will likely contain the following pattern: src="https://www.google.com/recaptcha/enterprise.js"> or src="https://www.google.com/recaptcha/releases/enterprise/...">

    
        // Inspect the script tag for reCaptcha version patterns
        // reCaptcha V2: src="https://www.google.com/recaptcha/api.js"
        // reCaptcha V3: src="https://www.google.com/recaptcha/enterprise.js"
    

Step 4: Verify the reCaptcha Version (Optional)

If you’re still unsure about the reCaptcha version, you can try verifying it using the following methods:

1. Check the website’s HTML structure: reCaptcha V3 often uses an invisible iframe, whereas reCaptcha V2 uses a visible checkbox.

2. Use the browser’s network requests: In the developer console, switch to the “Network” tab and reload the webpage. Look for reCaptcha-related requests. reCaptcha V3 often sends requests to www.google.com/recaptcha/enterprise/..., whereas reCaptcha V2 sends requests to www.google.com/recaptcha/api.js.

    
        // Verify reCaptcha version using HTML structure and network requests
        // reCaptcha V3: invisible iframe and requests to www.google.com/recaptcha/enterprise/...
        // reCaptcha V2: visible checkbox and requests to www.google.com/recaptcha/api.js
