Logging into Gmail using Python with detecting failed login

I know that multiple people have asked a similar question about this however, I would like to know how to login to gmail (or google account) using python. I have a code already (see below) that can loggin the user to gmail using selenium. However I noticed a few problems.

The browser closes when the program stops/closes.
It can not detect a failed login.

Both problems really need to be solved for me to be able to work on my project. I don't mind using something else than selenium like pyautogui to open google. However, it needs to be able to detect a failed login and then close the browser, if the login is successful the browser should stay open for the user to use.

My code:

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

def gmail_login(username, password):
    gmailId = username
    passWord = password
    driver = webdriver.Chrome(ChromeDriverManager().install())
    try:
        driver.get(r'https://accounts.google.com/signin/v2/identifier?continue=' + \
                   'https%3A%2F%2Fmail.google.com%2Fmail%2F&service=mail&sacu=1&rip=1' + \
                   '&flowName=GlifWebSignIn&flowEntry = ServiceLogin')
        driver.implicitly_wait(3)

        loginBox = driver.find_element_by_xpath('//*[@id ="identifierId"]')
        loginBox.send_keys(gmailId)

        nextButton = driver.find_elements_by_xpath('//*[@id ="identifierNext"]')
        nextButton[0].click()

        passWordBox = driver.find_element_by_xpath(
            '//*[@id ="password"]/div[1]/div / div[1]/input')
        passWordBox.send_keys(passWord)

        nextButton = driver.find_elements_by_xpath('//*[@id ="passwordNext"]')
        nextButton[0].click()

    except:
        driver.close()


gmail_login("[email protected]", "Password")

I tought of checking the url after the program has finished if it is equal to a logged in url however that didn't really work too well and now I am out of ideas.

Solution

Updated 02-14-2021

I was able to extract this error message:

using this code:

signin_failure = driver.find_elements_by_xpath("//*[contains(text(),'Couldn’t sign you in')]")
if signin_failure[1].text == 'Couldn’t sign you in':
   print('something went wrong')

In a normal gmail login you will get one of these two error messages:

Couldn’t find your Google Account
Wrong password. Try again or click Forgot password to reset it

The XPATH to get these error messages is:

wrong_email = driver.find_elements_by_xpath("//*[contains(text(),'Couldn’t find your Google Account')]")

wrong_password = driver.find_elements_by_xpath("//*[contains(text(),'Wrong password. Try again or click Forgot password to reset it')]")

if you want to close the browser after an error message, such as Couldn’t sign you in then add a driver.close() statement.

signin_failure = driver.find_elements_by_xpath("//*[contains(text(),'Couldn’t sign you in')]")
if signin_failure[1].text == 'Couldn’t sign you in':
   print('something went wrong')
   driver.close()

If you want to keep the browser open then don't use the driver.close() statement, but add this experimental_option

chrome_options.add_experimental_option("detach", True)

I was also able to throw these error messages:

signin_failure = driver.find_elements_by_xpath("//*[contains(text(),'Couldn’t sign you in')]")

# this message was throw when the next button was clicked prior to entering a username
no_input = driver.find_elements_by_xpath("//*[contains(text(),'Enter a valid email of phone number')]")

PSEUDOCODE CODE:

This is how you could do it, but you might have to adjust the code as you test.

def gmail_login(username, password):
    driver = webdriver.Chrome(ChromeDriverManager().install())
    try:
        driver.get(r'https://accounts.google.com/signin/v2/identifier?continue=' + \
                   'https%3A%2F%2Fmail.google.com%2Fmail%2F&service=mail&sacu=1&rip=1' + \
                   '&flowName=GlifWebSignIn&flowEntry = ServiceLogin')
        driver.implicitly_wait(3)

        loginBox = driver.find_element_by_xpath('//*[@id ="identifierId"]')
        loginBox.send_keys(username)

        nextButton = driver.find_elements_by_xpath('//*[@id ="identifierNext"]')
        nextButton[0].click()

        wrong_email = driver.find_elements_by_xpath("//*[contains(text(),'Couldn’t find your Google Account')]")

        # you need to check this slice
        if wrong_email[1].text == 'Couldn’t find your Google Account':
            print('something went wrong')
            driver.close()

        else:
            passWordBox = driver.find_element_by_xpath('//*[@id ="password"]/div[1]/div / div[1]/input')
            passWordBox.send_keys(password)

            nextButton = driver.find_elements_by_xpath('//*[@id ="passwordNext"]')
            nextButton[0].click()

            wrong_password = driver.find_elements_by_xpath("//*[contains(text(),'Wrong password. Try again or click Forgot password to reset it')]")

            # you need to check this slice
            if wrong_password[1].text == 'Wrong password. Try again or click Forgot password to reset it':
                print('something went wrong')
                driver.close()

    except:
        driver.close()

Google forbids using automated scripts for logging into Gmail. I have tried using selenium and I get this warning.

When I click Learn More I get this message.

Please note this line: Are being controlled through software automation rather than a human

Here are other question where they discuss work arounds for this Google direct login issue:
