How can I bypass the Google CAPTCHA with Selenium and Python?
To start with using Selenium's Python clients, you should avoid solving/bypass Google CAPTCHA.
Selenium
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.
CAPTCHA
On the other hand, CAPTCHA (the acronym being ...Completely 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
time.sleep(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:

- Find the reCAPTCHA element and click on it — Python + Selenium

How to bypass ReCaptcha with buster extension using Selenium and Python
The Buster icon is within another sibling <iframe>
. So you have to:
Switch back to the default_content().
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use the following Locator Strategies:
Code Block:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
driver.switch_to.default_content()
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"//iframe[@title='recaptcha challenge']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//button[@id='solver-button']"))).click()Browser Snapshot:
