Python selenium: use a browser that is already open and logged in with login credentials

问题

Is there a way that for different runs of a python program that uses selenium I keep the browser that I have opened and logged in with my credentials, open and use in later runs?

I am debugging a code. On the browser each time I need to log in using my credentials. Currently, everytime I stop the code, the web-browser gets closed. Is there a way to keep a copy of browser that I have already open and logged in open and use it for my later debug so every time I don't need to enter my login credentials again?

My code that opens the browser looks like this:

driver = webdriver.Chrome(executable_path="/the_path/chromedriver", chrome_options=chrome_options) 
driver.get(url)

EDIT:

Actually, the way this website asks for authentication is as follows: First, it asks for the username, then I need to press the continue button, then it asks for the password, after entering the password, it sends an SMS to my phone, I need to enter it before it goes to the intended page.

Well, since this question is upvoted but my flag as duplicated question wasn't accepted I will post here the same exact answer I already posted for a similar question:

You can use pickle to save cookies as text file and load it after:

def save_cookie(driver, path):
    with open(path, 'wb') as filehandler:
        pickle.dump(driver.get_cookies(), filehandler)

def load_cookie(driver, path):
     with open(path, 'rb') as cookiesfile:
         cookies = pickle.load(cookiesfile)
         for cookie in cookies:
             driver.add_cookie(cookie)

With a script like:

from selenium import webdriver
from afile import save_cookie

driver = webdriver.Chrome()
driver.get('http://website.internets')

foo = input()

save_cookie(driver, '/tmp/cookie')

What you can do is:

1. Run this script
2. On the (selenium's) browser, go to the website, login
3. Go back to your terminal, type anything hit enter.
4. Enjoy your cookie file at /tmp/cookie. You can now copy it into your code repo and package it into your app if needed.

So, now, in your main app code:

from afile import load_cookie

driver = webdriver.Chrome()
load_cookie(driver, 'path/to/cookie')

And you are now logged.

This was a feature request and closed as not feasible. But is a way to do it, use folders as profiles and keep all logins persistent from session to session by using the Chrome options user-data-dir in order to use folders as profiles, I run:

chrome_options = Options()
chrome_options.add_argument("user-data-dir=selenium") 
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("www.google.com")

You can manually interact at this step with the opened window and do the logins that check for human interaction, check remember password etc I do this and then the logins, cookies I need now every-time I start the Webdriver with that folder everything is in there. You can also manually install the Extensions and have them in every session. Second time I run, with exactly the same code as above, all the settings, cookies and logins are there:

chrome_options = Options()
chrome_options.add_argument("user-data-dir=selenium") 
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("www.google.com") #Now you can see  the cookies, the settings, Extensions and the logins done in the previous session are present here

The advantage is you can use multiple folders with different settings and cookies, Extensions without the need to load, unload cookies, install and uninstall Extensions, change settings, change logins via code, and thus no way to have the logic of the program break, etc Also this is faster than having to do it all by code.
