How can I bypass the Google CAPTCHA using Selenium and Python?
When I try to scrape something, Google give me a CAPTCHA. Can I bypass the Google CAPTCHA with Selenium Python?
As an example, it’s Google reCAPTCHA. You can see this CAPTCHA via this link:
To start with using Selenium’s Python clients, you should avoid solving/bypass Google CAPTCHA.
Selenium automates browsers. Now, what you want to achieve with that power is entirely up to individuals, but primarily it is for automating web applications through browser clients for testing purposes and of coarse it is certainly not limited to that.
On the other hand, CAPTCHA (the acronym being mpletely Automated Public Turing test to tell Computers and Humans Apart… ) is a type of challenge–response test used in computing to determine if the user is human.
So, Selenium and CAPTCHA serves two completely different purposes and ideally shouldn’t be used to achieve any interrelated tasks.
Having said that, reCAPTCHA can easily detect the network traffic and identify your program as a Selenium driven bot.
Generic Solution
However, there are some generic approaches to avoid getting detected while web scraping:
The first and foremost attribute a website can determine your script/program by is through your monitor size. So it is recommended not to use the conventional Viewport.
If you need to send multiple requests to a website, keep on changing the User Agent on each request. Here you can find a detailed discussion on Way to change Google Chrome user agent in Selenium?
To simulate humanlike behavior, you may require to slow down the script execution even beyond WebDriverWait and expected_conditions inducing (secs). Here you can find a detailed discussion on How to sleep Selenium WebDriver in Python for milliseconds
This use case
However, in a couple of use cases we were able to interact with the reCAPTCHA using Selenium and you can find more details in the following discussions:

In order to bypass the CAPTCHA when scraping Google, you have to manually solve a CAPTCHA and export the cookies Google gives you. Now, every time you open a Selenium WebDriver, make sure you add the cookies you exported. The GOOGLE_ABUSE_EXEMPTION cookie is the one you’re looking for, but I would save all cookies just to be on the safe side.
If you want an additional layer of stability in your scrapes, you should export several cookies and have your script randomly select one of them each time you ping Google.
These cookies have a long expiration date so you wouldn’t need to get new cookies every day.

Captcha is to avoid those automated bots.. You can manually solve the captcha and you can continue the work.
Like this:
import time
from time import sleep
dus = input (‘Did you solve the captcha? 1 for yes 2 for no:’)
if dus == 1:
tdus = input (‘Did you solve the captcha? 1 for yes 2 for
if tdus == 1:

Clear Browsing History, cached data, cookies and other site data
First Create an Google Account while you are in browser window opened by selenium.
Sign in to your account
ndElement((“identifier”)). sendKeys(“Email”);
ndElement((“password”)). sendKeys(“Password”);
Then Open any website that uses recaptcha tick on checkmark using this code
String ndElement(By. tagName(“iframe”)). getAttribute(“name”);
wd. switchTo()(framename);
You won’t find any Puzzles or anything.

The simple solution is suspend the program for 10 seconds or more and then when the automated browser opens solve the reCAPTCHA on your own and then the program starts after 10 seconds and execute rest of the program like clicking submit button or other things

Bypass as in solve it or bypass as in never get it at all?
To solve it:
sign up with 2captcha, capmonster cloud, deathbycaptcha, etc. and follow their instructions. They will give you a token that you pass with the form.
To never get it at all:
Make sure you have good IP reputation (most important for Cloudflare).
Make sure you have a good browser fingerprint (most important for Distil) – I recommend puppeteer + the stealth plugin.

How to handle Captcha in Selenium | BrowserStack

As technology has become embedded in today’s world, digital security has been a major concern and for good reason. Hackers use bots to operate web applications and access data such as user email addresses that lead to spamming, posing threats to privacy. A measure to prevent such bot activity is to use Captcha (Completely Automated Public Turing test to tell Computers and Humans Apart). It is quite commonly used, which is why testers often search for means to test Captcha via Selenium. For testers seeking tips on testing “Selenium Captcha”, “Selenium ReCaptcha” and wondering “how to handle captcha in selenium”, this article will help. It will discuss how Captcha can be tested via Selenium by QA engineers. What is Captcha? Through Captcha, the user is asked to perform a certain task, such as enter the text written in the image or click on the images from a set of different images that match the required tasks are meant to ascertain whether the user is a human or a bot. Since the task is dynamic, it can only successfully be carried out with human cognizance and correct interpretation of information – areas where the artificial intelligence of bots tends to fail. Some variants of Captcha also support visually impaired individuals by generating audio instead of ’s open-source CAPTCHA widget, reCAPTCHA is widely used, since it supports major screen readers such as JAWS and NVDA for IE, Edge, or Chrome on Windows OS, ChromeVox for Chrome OS, and VoiceOver for Safari and Chrome on Mac OS. Handling Captcha Enabled Web Applications in SeleniumFor web applications with Captcha enabled, automated UI testing could be an issue, especially as the step involving Captcha can create a hindrance in a test scenario. Moreover, the idea of Captcha itself does not align with automation, as doing so will defeat the purpose of prohibiting bots from performing activities on the application. Thus, it is essential to efficiently handle Captcha in Selenium Testing to ensure that tests run seamlessly without any bottlenecks. While automating Captcha is not the best practice, there are three efficient ways of handling Captcha in Selenium:By disabling the Captcha in the testing environmentAdding a hook to click the Captcha checkboxBy adding a delay to the Webdriver and manually solve Captcha while testingHow to Disable Captcha in the Test EnvironmentDisabling Captcha in the test environment would ensure that while testing a web application, the Captcha task is not required. While using Google’s open-source Captcha widget – reCAPTCHA v2, put in the Site Key and the Secret Key, (known as the test keys). As a result, all verification requests will pass, and automated UI testing can be conducted seamlessly. Site key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhISecret key: 6LeIxAcTAAAAAGG-vFI1TnRWxMZNFuojJ4WifJWeHowever, while doing so, the reCAPTCHA widget will show a warning alert that ensures that the CAPTCHA is bypassed only for testing purposes and not in real-time access by users. In the case of reCAPTCHA v3, the user needs to create a separate key for testing environments. Unlike reCAPTCHA v2, which has a generic testing key to support, reCAPTCHA v3 requires creating separate keys for the testing environment. Users can create keys for reCAPTCHA v3 is recommended to create one site key per web or mobile application. However, one can create separate site keys for staging and production environments. This is because there is a risk of contaminating reCAPTCHA risk analysis with the data from the test environment, which might alter the results of the to click the checkbox in reCaptcha during Selenium testingBy adding a hook to the code, users can bypass the Captcha while performing Automation Testing. The Captcha recognizes a bot clicking the checkbox element by the fact that it takes less time for the bot to click as compared to humans. Therefore, testers need to induce WebDriverWait, so that the element is clicked only when it becomes clickable. This bypasses the ’s the code to add a hook that clicks on reCAPTCHA using Selenium and Java-public class ReCaptcha_click {
public static void main(String[] args) {
tProperty(“”, “C:\\Utility\\BrowserDrivers\\”);
ChromeOptions options = new ChromeOptions();
WebDriver driver = new ChromeDriver(options);
new WebDriverWait(driver, 10)(ameToBeAvailableAndSwitchToIt((“//iframe[starts-with(@name, ‘a-‘) and starts-with(@src, ”)]”)));
new WebDriverWait(driver, 20)(ExpectedConditions. elementToBeClickable(By. cssSelector(“captcha-checkbox-checkmark”)))();}}How to add delay and manually solve Captcha during Automation TestingFirstly, this method is not completely automated and requires human intervention to solve the Captcha. Call it a semi-automated test. In this method, a delay of 10-20s is introduced to freeze the captcha screen, so that the page does not suffer from the race condition, which generally happens while using automation testing on a web page with a Captcha element. This is because automation testing is much faster than the focus on reCAPTCHA. Thereby, the password is entered much before the reCAPTCHA element even gets ready, leading to flaky tests. By adding a delay to the testing, it ensures that by the time reCAPTCHA is ready, the form fill-up action waits and the racing condition can be evaded tactfully, streamlining the test and making it more delay execution of Selenium Webdriver for 10 seconds using Python, use the following command import time
(10)Here’s how delay can be added using Puppeteer for headless browsers:const puppeteer = require(‘puppeteer’);
const chromeOptions = {
defaultViewport: null};
(async function main() {
const browser = await (chromeOptions);
const page = await wPage();
await (”);})()
await (‘#user_reg’, ‘some_username’);
await (‘#passwd_reg’, ‘[email protected]’);
await (‘#passwd2_reg’, ‘[email protected]’);
await (‘#register-form button[type=submit]’);
defaultViewport: null,
slowMo:15, };Captcha, which has been an important UI element to restrict bots from accessing a web application, has posed a major challenge for the testers performing UI testing using automating Captcha would defeat the purpose of having Captcha in the first place to ensure human interaction with the UI, it is very tricky to handle Captcha in Selenium. Try Selenium Testing for FreeHowever, with the test keys and hook, it is possible to ensure that the Captcha does not hamper UI testing. Captcha handling in Selenium is a mandatory skill of QAs because of how frequently Captcha is used as a security measure. Ideally, it is recommended as a best practice to separate the test cases involving Captcha and run them separately. Additionally, if the tests are not conducted on the live code that is deployed already, then the testers could disable the Captcha module when they perform automated UI in mind that Selenium tests must be run on real devices for accurate results. Start running tests on 2000+ real browsers and devices on BrowserStack’s real device cloud. Run parallel tests on a Cloud Selenium Grid to get faster results without compromising on accuracy. Testers can also conduct Cypress testing on 30+ real browser versions across Windows and macOS. Detect bugs before users do by testing software in real user conditions with BrowserStack.
How to avoid triggering google captcha while browsing in a ...

How to avoid triggering google captcha while browsing in a …

Preface: my goal is not to solve captcha using automation tools, but to attempt to understand why a browser that is being launched by selenium is being identified as a bot in the first place, and how selenium contributes to this.
I use selenium to start up firefox and log onto a website to scrape some data a few times a day.
Recently the website changed their login system by adding google’s reCAPTCHA, and everytime I try to click the checkbox, google determines that I am a bot and asks me to select a bunch of images.
I started up a regular instance of firefox (that is, without selenium), went to the website, clicked the checkbox, and it determined that I was a human and let me go.
I then became curious what was the difference between me launching firefox through the executable, and me launching firefox through selenium. I decided to launch firefox using this piece of java code
WebDriver driver = new FirefoxDriver(new FirefoxProfile());
So I’m doing nothing much but starting firefox, using selenium. Which of course means a lot of stuff is going on under the hood, but perhaps the selenium instance of firefox is not “human” enough?
So I tried a few different things to try to look more human:
Maybe I just need to browse. Like a human.
There are many theories that talk about things like mouse movement, keyboard strokes, etc. So the browser starts up, I type in the URL, I click a few other links, I come back to the login page, type in username + password, then proceed to click on the captcha I’m a bot.
Maybe I don’t have any cookies or browsing history?
Selenium by default creates a new profile, so it has no cookies or browsing history. I can specify a custom profile to use, so I simply passed in my own firefox profile stored in APPDATA/roaming/mozilla/profiles. I verified that all of the websites that I have saved my credentials were there in the selenium-launched browser, but when I confronted the reCAPTCHA, it determined I was a bot and asked for image selection
Maybe I need to use caching?
By default, selenium uses a custom cache path that is cleaned up after the session is over. In firefox you can see this by going to about:cache and it will say something like anonymous6337741624277931373webdriver-profile\cache2, and there isn’t much there.
So I decided to use my own profile’s cache
tPreference(“”, PATH_TO_MY_PROFILE_CACHE);
And verified that all of my cached resources are there.
But it didn’t make a difference.
Maybe I just need to solve the captcha once?
Now I’m thinking, OK, so if google thinks I’m a bot, how about I solve the captcha in the selenium-launched browser once, let them know I’m good, and then it won’t happen again? Maybe it identifies the browser as a new client, and just needs to know that this new client is not a bot.
So I solve the captcha and successfully log in. Then I logged out, returned to the login page, entered my credentials, pressed the reCAPTCHA it asked me to solve the image selection problem again!
At this point I’m thinking, I just solved the captcha successfully half a minute ago, exhibited a bunch of manual human actions, but I’m still being identified as a bot.
Is there something specific about selenium that’s making google identify me as a bot automatically?
I have used a custom profile, with custom cache path. I use cookies. I have all my regular extensions that I have installed on my profile. My user agent is unspoofed and it’s no different from my normal browsing experience. There’s nothing in the request headers that would suggest it is any different from a regular browser.
I would conclude that there is something on selenium’s end that is causing me to be identified as a bot, when I’m using the browser as a regular user.
Perhaps there are specific JS objects that are injected into the DOM that google picks up on?
