How to use authenticated proxy in selenium chromedriver?

Each Answer to this Q is separated by one/two green lines.

After searching for many hours I am starting to think this is impossible.

I need to run Chrome through selenium using different authenticated (not public) proxy’s for each run.

PROXY_IP = "<some IP address>"
UID = "<the user id>"
PWD = "<the password">

options = webdriver.ChromeOptions()
options.add_argument("--proxy-server=%s:%[email protected]%s" % (UID,PWD,PROXY_IP))

driver = webdriver.Chrome(executable_path=".\\driver\\chromedriver.exe",
                          chrome_options=options)
driver.get("<site URL>")

Chrome will fire-up and display the error:

This webpage is not available
ERR_NO_SUPPORTED_PROXIES

If I use a public proxy requiring no authentication like this…

PROXY_IP = "<public proxy IP address>"

options = webdriver.ChromeOptions()
options.add_argument("--proxy-server=%s" % PROXY_IP)

driver = webdriver.Chrome(executable_path=".\\driver\\chromedriver.exe",
                          chrome_options=options)
driver.get("<site URL>")

…it runs just fine and displays the site while using the proxy.

I also tried a variant with http:// in front of the user ID:

options.add_argument("--proxy-server=http://%s:%[email protected]%s" % (UID,PWD,PROXY_IP))

The fact that I have searched far and wide and haven’t found a solution leads me to believe none might exist.

I did find this but I can’t make sense out of it:

selenium chromedriver authentication proxy

Not sure what browswermob-proxy is or is supposed to do or how to implement and test in Python. I hate piling up band-aid solutions unless they are absolutely necessary.

EDIT (08NOV21):

I have been away from using Selenium for many years. Because of this I now lack the context (and time, sorry) to go through the newer answers being provided and mark one as the solution to this problem. Does SO have a mechanism one could use to effectively delegate this function to someone who might be a current practitioner with expertise in this domain?

To use proxies with auth in python selenium you can use seleniumwire.

Fistly, install it with pip install selenium-wire

Then import webdriver from seleniumwire instead selenium

from seleniumwire import webdriver
options = {
    'proxy': {
        'http': 'http://username:[email protected]:port', 
        'https': 'https://username:[email protected]:port',
        'no_proxy': 'localhost,127.0.0.1' # excludes
    }
}
browser = webdriver.Chrome(path_to_driver, seleniumwire_options=options)

Now you can use your browser instance exact the same way as selenium: browser.get('https://api.ipify.org') and so on…

I have checked for most of the solutions on the web and for none of them authentication via chrome/firefox desired capabilities is working. Check this link: https://github.com/webdriverio/webdriverio/issues/324. Finally the temporary solution is to whitelist your IP address with the proxy provider.

This is the best solution I found and is the ONLY one that worked – all other answers on this question are outdated. It basically generates an auth extension for Chrome on the fly. Simply use the function as defined in the script as follows:

driver = proxy_chrome(host, port, username, password)
driver.get("http://www.icanhazip.com/")
driver.get("https://www.reddit.com/")
print('Terminated without issues.')

Note that this doesn’t work with the –headless option. However, on Linux, you can simply use the x virtual frame buffer to simulate that. It’s as easy as this in python:

import xvfbwrapper
x = xvfbwrapper.Xvfb()
x.start()

after trying many solutions that didn’t actually work properly, i finally managed to set the authenticated proxy using the suggested extension from previous answers.
what you need to do is to enter this link:

http://crxextractor.com/
and paste this url:
https://www.crx4chrome.com/crx/1446/

It will let you download the extention as a .crx file without installing it.
than i used this code:

proxy = {'address': 'pr.oxylabs.io:7777',
     'username': 'USERNAME',
     'password': 'PASSWORD'}

capabilities = dict(DesiredCapabilities.CHROME)
capabilities['proxy'] = {'proxyType': 'MANUAL',
                         'httpProxy': proxy['address'],
                         'ftpProxy': proxy['address'],
                         'sslProxy': proxy['address'],
                         'noProxy': '',
                         'class': "org.openqa.selenium.Proxy",
                         'autodetect': False,
                         'socksUsername': proxy['username'],
                         'socksPassword': proxy['password']}

options = webdriver.ChromeOptions()
options.add_extension("./extension_2_0_0_0.crx")
driver = webdriver.Chrome(executable_path=CHROME_PATH, desired_capabilities=capabilities, chrome_options=options)

I could not find any solution for chrome. We can not add extensions with headless option.
I am using Heroku with chrome-buildpack. There are following options

  1. Use xvfb instead of headless options and install extension
  2. Use local proxy forwarder that forwards traffic to authenticated proxy; we can use Squid, mitProxy, or something like proxy-login-automator

Instead of these workaround I switched to Firefox where i was able to fill Username and Password on Proxy authentication Pop-up. Like given below. Following code is for Ruby using Capybara. You should be able to do something like this on your platform


page.driver.browser.switch_to.alert.send_keys('proxy-username' + Selenium::WebDriver::Keys::KEYS[:tab] + 'my-password')
page.driver.browser.switch_to.alert.accept

I tryed lot of time to do the same.

Chrome is using only proxy of the OS where it is installed. You can check it by going to options-> find: proxy -> change proxy settings

So without additional addons and configuring this addons you cannot do this.

Or you can change your OS proxy settings — this is much easier.

Also you can use phantomjs — it have the same engine(WebKit) as chrome.
using something like this:

String PROXY = proxyIP + ":" + proxyPort;
String proxyAuth= proxyUser + ":" + proxyPass;
        OpenQA.Selenium.Proxy proxy = new OpenQA.Selenium.Proxy();
                    proxy.HttpProxy = PROXY;
                    proxy.FtpProxy = PROXY;
                    proxy.SslProxy = PROXY;
                    proxy.SocksProxy = PROXY;

    var serviceJS = PhantomJSDriverService.CreateDefaultService(phantomPath);
    serviceJS.AddArguments("--proxy=" + PROXY, "--proxy-type=http", "--proxy-auth=" + proxyAuth);

THis is a temporary solution might work in initial state:
Code is in Python:
Download the plugin first from chrome plugin store : Proxy-Auto-Auth_v2.0.crx

        options = webdriver.ChromeOptions()
        options.add_extension("./Proxy-Auto-Auth_v2.0.crx")) #this will provide you a window to enter user name and proxy 
        driver = webdriver.Remote(command_executor=selenium_server,desired_capabilities=options.to_capabilities())

        or 

        driver = webdriver.Chrome(chrome_options=options)

I have been searching extensively. This is what it works for me

1ยบ If you always use the same IP you can speak with your proxy provider to access proxy with your IP = no user or password needed. In my experience that’s easier.

If that’s not possible other solution is:
pip install undetectable chromedriver and seleniumwire if you don’t have them

selenium-wire 4.5.6
selenium 4.1.0
undetected-chromedriver 2.2.1

from seleniumwire.undetected_chromedriver.v2 import Chrome

options = {
    'proxy': {
        'http': 'http://user:[email protected]:port',
        'https': 'https://user:[email protected]:port',
        'no_proxy': 'localhost,127.0.0.1'
    }
}

driver = Chrome(seleniumwire_options=options)

or you can also try another solution:

import undetected_chromedriver.v2 as uc

IP = XXXX
SOCKS5_PORT = XXXX
HTTPS_PORT = XXXX

options = uc.ChromeOptions()
options.add_argument(f'--proxy-server=socks5://{IP}:{SOCKS5_PORT}')
#you can substitue the last line for this one:
options.add_argument(f'--proxy-server=https://{IP}:{HTTPS_PORT}')

driver = uc.Chrome(executable_path=EXECUTABLE_PATH, options=options)
