To ensure that you are not a robot, CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a challenge-response test.
Spamming, scraping data and launching denial-of-service attacks are some of the things that websites can be protected from bots and other automated software.
Some forms of CAPTCHAs include text-based, image-based reCAPTCHAs as well as behavioural CAPTCHAs which analyze user interactions; they may be secure but difficult for some users hence we need more user friendly inclusive alternatives.
What is a CAPTCHA?
A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a challenge-response test to see if you are human or not.
CAPTCHAs prevent automated systems from abusing online services by creating fake accounts or spamming or scraping content. Tests often require users to do tasks that humans find easy but bots hard like identifying letters in distorted text or selecting images based on a prompt.
How It Works
CAPTCHAs work by presenting users with tasks that take advantage of the differences between humans and automated systems.
The most common types of captchas include:
- Text-based captchas: Users are asked to type in the characters shown in an image.
- Image-based captchas: Users are prompted to select images that match a certain criteria, like all images with traffic lights.
- Audio captchas: Users listen to a series of spoken letters or numbers and type them in a form.
- reCAPTCHA: A more advanced form of captcha developed by google often involves checking the box “I am not a robot” or more complex tasks like selecting images.
Common Problems and Solutions
How to Solve Problems
Solving Google captcha test requires understanding what type of code it is and what the challenge involves.
Here are general steps:
- Read Instructions: Make sure you understand what the captcha is asking for, like identifying objects in images or entering text.
- Refresh Captcha: If the captcha is unclear, click the refresh button to generate a new one.
- Use Accessible Options: If available, switch to audio captcha if the visual one is hard to read.
How to Solve Invalid Problems
Invalid code errors occur when the input does not match expected response. Here are tips:
- Check Typos: Make sure the entered text is exactly same as characters shown, including case sensitive.
- Use Different Browser: Sometimes browser settings or extensions can interfere with captcha. Try a different browser.
- Clear Browser Cache: Cached data could cause issues with captchas. Clear your browser cache and cookies then try again.
- Disable Extensions: Browser extensions especially those related to privacy or ad-blocking might interfere with captcha. Temporarily disable extensions to see if it solves the issue.
How to Solve Captcha in Selenium Python
Solving tests in python using selenium involves automating interaction with the captcha. Here are steps:
- Automate Form Filling: Use Selenium to fill out forms and handle captcha pop-ups.
- Integrate Captcha Solvers: Use CAPTCHA-solving services that uses APIs to solve CAPTCHAs automatically.
- Manual Intervention: If automation is not possible, design automation script to pause and let user solve captcha manually.
How to Enter Code Correctly
Paying attention to detail is necessary for entering a challenge. Here are some tips:
- Type What You See: Enter the characters as they appear, including case sensitive and special characters.
- Refresh if Needed: If the CAPTCHA is hard to read, refresh the page to get a new one.
- Use Audio: If you have difficulty with the visual CAPTCHA, use the audio option if available.
How to Get Code
Websites generate and display codes when they are used. You do not need to acquire them from elsewhere; they will automatically show up during form submission or login process.
What is an Example?
A typical example of a CAPTCHA may be an image displaying distorted text, such as “X7J9M” which must be entered into a text box by user. Another example would be selecting all images that contain traffic lights from set of images.
How to Create Code
To create a code, you need captcha that generates random challenges and verifies user responses. This usually involves:
- Generate Random Challenges: Create random text or images for the CAPTCHAs.
- Display the challenge: Use HTML/CSS on your webpage.
- Verify Responses: Implement server-side logic to check against generated captchas.
How to Activate Account
In order activate captcha account follow this steps:
- Register on the captcha provider’s website – sign up for an account and register your site
- Get API Keys – obtain site key and secret key for implementing captcha
- Integrate Captcha into Your Site – use provided keys along with integration instructions given by reCAPTURE so as add captchas to your forms
How to Complete Code
To complete a CAPTCHA:
- Follow the Prompt: Read the instructions and perform the required task, such as entering text or selecting images.
- Submit the Response: Enter your response in the provided field and proceed with your form submission or login.
How to Manually Test
Manually testing CAPTCHA involves interacting with it as a user would. Here are the steps:
- Access the CAPTCHA-Enabled Form: Navigate to the form or login page with the CAPTCHA.
- Complete the CAPTCHA: Enter the required information or select the correct images as prompted.
- Submit the Form: Ensure that the CAPTCHA verification works correctly and allows you to proceed.
How to Fill Out a Code Automatically
Filling out a CAPTCHA code automatically can be done using automation tools like Selenium with CAPTCHA-solving services. However, this should be used responsibly and ethically, complying with the terms of service of the websites being accessed.

Enter the characters exactly as shown, paying attention to case sensitivity and any special characters. Use the refresh button or audio option if needed.
CAPTCHA codes are provided by the websites requiring verification. They appear automatically during form submission or login processes.
Examples include entering distorted text like “X7J9M” or selecting images containing traffic lights from a set of pictures.
CAPTCHAs work by presenting tasks that are easy for humans but difficult for bots, such as typing distorted text or selecting images.
A CAPTCHA code on your phone functions similarly to a desktop CAPTCHA, ensuring the request is made by a human.
