How to handle authentication popup with Selenium WebDriver using Java?

We can handle authentication popup with Selenium. To do this, we have to pass the user credentials within the URL. We shall have to add the username and password to the URL.

Syntax

https://username:password@URL
https://admin:admin@the−nternet.herokuapp.com/basic_auth
Here, the admin is the username and password.
URL − www.the-internet.herokuapp.com/basic_auth

Let us work and accept the below authentication popup.

Example

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class AuthnPopup{
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver",
      "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String u = "admin";
      // adding username, password with URL
      String str = "https://" + u + ":" + u + "@" +
      "the-internet.herokuapp.com/basic_auth";
      driver.get(str);
      // identify and get text after authentication of popup
      String t = driver.findElement(By.cssSelector("p")).getText();
      System.out.println("Text is: " + t);
      driver.quit();
   }
}

Output
