How to Load Default Profile in Chrome Using Python Selenium Webdriver

How to load default profile in Chrome using Python Selenium Webdriver?

This is what finally got it working for me.

from selenium import webdriver

options = webdriver.ChromeOptions() 
options.add_argument("user-data-dir=C:\\Path") #Path to your chrome profile
w = webdriver.Chrome(executable_path="C:\\Users\\chromedriver.exe", chrome_options=options)

To find path to your chrome profile data you need to type chrome://version/ into address bar . For ex. mine is displayed as C:\Users\pc\AppData\Local\Google\Chrome\User Data\Default, to use it in the script I had to exclude \Default\ so we end up with only C:\Users\pc\AppData\Local\Google\Chrome\User Data.

Also if you want to have separate profile just for selenium: replace the path with any other path and if it doesn't exist on start up chrome will create new profile and directory for it.

How to use certain Chrome profile with selenium python?

First of all

update your ChromeDriver to the latest version

(This part is mandatory).
Then pass two arguments --profile-directory=Profile 1 and user-data-dir=C:\\Users\\user123\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 16 to the Chrome binary

options = Options()
options.add_argument('--profile-directory=Profile 16')
options.add_argument("user-data-dir=C:\\Users\\Hana\\AppData\\Local\\Google\\Chrome\\User Data\\") #Path to your chrome profile
driver = webdriver.Chrome(executable_path="C:\\chromedriver.exe", options=options)

Note that in user-data-dir you should only pass the path of all profiles then the name of specific profile (Here, Profile 16) should be passed through --profile-directory

You can check out full source code named PythonChromeProfile in SeleniumWebDriver-Tiny_projects on Github, Which I tested successfuly. Also you can read about creating Chrome profiles and find the path to that profile Here

How to load default profile with Selenium when Chrome is already open?

The answer is you cannot open two session with 1 user-directory. Web-driver won't let you do this, It is like to rename a file in Windows when the file is open.

If you want to open chrome without user-dir, you can simply open with --incognito it will not store anything or use user-dir.

Otherwise you have to close the session with driver.quit() at the end of the test (teardown). So you can run the next test without problem.
Or you can use another user direcotry path, so the sessions will not interfers each other

How to use Chrome Profile in Selenium Webdriver Python 3

As per your question and your code trials if you want to open a Chrome Browsing Session here are the following options:

To use the default Chrome Profile:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Default")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")

Note: Your default chrome profile would contain a lot of bookmarks, extensions, theme, cookies etc. Selenium may fail to load it. So as per the best practices create a new chrome profile for your @Test and store/save/configure within the profile the required data.

To use the customized Chrome Profile:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")
