How to deal with prompt alert for using Selenium Webdriver

Question

I am using Selenium Webdriver to validate a specific site and upon going to the site, it prompts me to enter a username and password via a prompt window. i cannot right click it to inspect properties

Prompt Window Screenshot:

I already tried the driver.switchTo().alert() and the Webdriver Wait but it still wont work. tried both on Chrome and firefox browsers

public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver","C:\\Users\\eclipse-workspace\\ChromeDemo\\geckodriver.exe");
        WebDriver driver = new FirefoxDriver ();
        //Go to Website
driver.get("enter site here");
//After entering the site, Prompt window appears
driver.switchTo().alert();
driver.findElement(By.name("User Name:")).sendKeys("nUsername");
driver.findElement(By.name("Password:")).sendKeys("nPassword");

I expect that the prompt window will be populated with the username and password but it doesn't

Answer 1

Try accessing the URL with username and password in below format, this will not show you the alert url: http://username:password@siteURL

driver.get(url)
