Automation Google login with python and selenium shows This browser or app may be not secure

First of all don't use chrome and chromedriver. You need to use Firefox.(if not installed) Download and install Firefox. Login to Google with normal Firefox.

You need to show the Google site that you are not a robot. You can use code like this:

from selenium import webdriver
import geckodriver_autoinstaller
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

geckodriver_autoinstaller.install()

profile = webdriver.FirefoxProfile(
    '/Users/<user name>/Library/Application Support/Firefox/Profiles/xxxxx.default-release')

profile.set_preference("dom.webdriver.enabled", False)
profile.set_preference('useAutomationExtension', False)
profile.update_preferences()
desired = DesiredCapabilities.FIREFOX

driver = webdriver.Firefox(firefox_profile=profile,
                           desired_capabilities=desired)

This can help you find your profile location.

But, why Firefox?

Actually there is only one reason, chromedriver was coded by Google.
They can easily understand if it is a bot or not. But when we add user data with Firefox, they cannot understand if there is a bot or not.

You can fool Google like this. It worked for me too. I tried very hard to do this. Hope it will be resolved in you too.

How to handle browser or app may not be secure issue with web driver Selenium python?

This issue was because of the selenium chrome profile.
I have created a new chrome profile and logged into it with the email id with which I was facing this issue. Then Turn on sync.

With this chrome profile in place I can skip the login steps and directly do the main process.
Use: Chrome Options to add newly created chrome profile as an argument.

Hope this helps people who are facing similar challenge.

Google: Couldn't Sign you in (the browser or app may be insecure) using selenium automation

For anyone facing this, the easiest way is to use cookies.

Download Colab's Cookies for that particular account.

In selenium, add them to your webdriver first and then go to the notebook link.
