How to Handle "Authentication Required" Pop-up in selenium [duplicate]

You can check for alert popup. for this you need to import following,

import org.openqa.selenium.security.UserAndPassword;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

First you need to wait until that pop up is coming.

WebDriverWait wait = new WebDriverWait(driver, 30);

Then check for alert popup is present/visible or not

Alert alertPopUp = wait.until(ExpectedConditions.alertIsPresent()); 

Then you can use authenticateUsing method of selenium web driver.

alertPopUp.authenticateUsing(new UserAndPassword("your_username", "your_password"));

There is also anoother way to to quick check, If you want to just verify present of alert

try {
  Alert alert = driver.switchTo().alert();
  alert.accept();

 } catch (NoAlertPresentException e) {
   // Alert not available
   e.printStackTrace();
 }

I got this working in IE using the below code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.Ie()
driver.get("https://scdm.corp.vha.com")
alert = driver.switch_to_alert()
alert.authenticate("username","password")
time.sleep(20)
driver.close()

Recently I came across this issue while testing the The-Internet Basic authentication Pop-Up. The solution is

driver.get('http://admin:[email protected]/basic_auth')

Add the username and password in the URL itself. I tried it in chrome and firefox both are working.

Copy these 2 files.

name this file manifest.json

{
  "manifest_version": 2,
  "name": "Authentication for ...",
  "version": "1.0.0",
  "permissions": ["<all_urls>", "webRequest", "webRequestBlocking"],
  "background": {
    "scripts": ["background.js"]
  }
}

this one background.js

var username = "your_username";
var password = "your_password";
var retry = 3;

chrome.webRequest.onAuthRequired.addListener(
  function handler(details) {    
    if (--retry < 0)
      return {cancel: true};
    return {authCredentials: {username: username, password: password}};
  },
  {urls: ["<all_urls>"]},
  ['blocking']
);

Zip these files together and put in your project directory, then encode with Base64 and use it as a Selenium extension

private String setUpAuthenticationExtension() {
            byte[] zipBytes;
            try {
                zipBytes = Files.readAllBytes(Path.of("authentication zip file"));
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
            return Base64.getEncoder().encodeToString(zipBytes);
        }


ChromeOptions chromeOptions = commonChromeOptions();

chromeOptions.addEncodedExtensions(setUpAuthenticationExtension());


WebDriver driver = new ChromeDriver(chromeOptions);
