Why Does Windows Authentication Fail in Selenium with Incorrect Credentials?

Windows Authentication Fails with Incorrect Username and Password

Users attempting to enter data using Selenium may encounter errors when handling Basic Authentication due to incorrect username and password credentials. The example provided below showcases this issue:

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.Firefox()
url = "http://the-internet.herokuapp.com/basic_auth"
driver.get(url)
time.sleep(5)
alert = driver.switch_to.alert
alert.authenticate('admin','admin')
time.sleep(4)
alert.accept()

To resolve this issue, an alternative approach can be used when working with specific versions of Selenium, geckodriver, and Firefox browsers. Instead of relying on pop-up authentication, the username and password can be seamlessly embedded within the URL itself:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('C:\Program Files\Mozilla Firefox\firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, executable_path="C:\Utility\BrowserDrivers\geckodriver.exe")
driver.get("http://admin:[email protected]/basic_auth")

This approach should successfully open the specified URL and authenticate with the provided credentials.
