I need to open a site that contain authentication alert. To handle that alert I tried following code but no success:

try {
    WebDriverWait wait = new WebDriverWait(driver, 100);
    Alert alert = driver.switchTo().alert();
     alert.authenticateUsing((Credentials) new UsernamePasswordCredentials("username", "pass"));
} catch (Exception e) {
    System.out.println("Alert not found");

Exception occur is:

Expected condition failed: waiting for alert to be present (tried for 100 second(s) with 500 MILLISECONDS interval)

enter image description here

  • Are you sure it's an alert and not a modal?

1 Answer 1


If I'm not mistaken, that's a basic authenticatin popup.

The easy way to bypass this in Selenium tests is to insert the username and password in the URL, like so:

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

More info: http://elementalselenium.com/tips/13-work-with-basic-auth Let me know if this works for you!

Alternative 1 Using AutoIt, or Windows API which is same as alternative 3 but proper code. See the answers in this StackOverflow topic.

Alternative 2 See Mike's answer in this StackOverflow topic on how to create a Chrome extension to bypass the popup

Alternavite 3 (works but quick & dirty)

using System.Windows.Forms
  • Okay I just tried your solution, site successfully opened but again the popup raised
