Need help with CAC card pop up click Cancel with Selenium

I need to write some code with selenium that can Cancel a user from a virtual smart card. This is a sample smart card like the one below.

To handle the CAC (Common Access Card) or virtual smart card pop-up and click “Cancel” using Selenium, follow these steps:

Understanding the Issue

CAC/smart card dialogs are system-level pop-ups (not part of the webpage DOM), so Selenium cannot interact with them directly. However, you can configure the browser to automatically bypass or cancel these prompts.

Solution 1: Disable Client Certificates (Chrome)

Add the --disable-client-certificates flag to ChromeOptions. This prevents the browser from prompting for certificates:

ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-client-certificates");
WebDriver driver = new ChromeDriver(options);

Solution 2: Auto-Cancel via Browser Preferences (Firefox)

For Firefox, set the certificate preference to never ask:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("security.default_personal_cert", "Do not ask");
WebDriver driver = new FirefoxDriver(profile);

Solution 3: Use a Pre-Configured Browser Profile

Create a Chrome profile that never prompts for certificates:

ChromeOptions options = new ChromeOptions();
options.addArguments(
  "--user-data-dir=C:/ChromeProfile",
  "--disable-client-certificates"
);
WebDriver driver = new ChromeDriver(options);

Solution 4: Headless Mode (If Applicable)

Run tests in headless mode (some browsers suppress dialogs):

ChromeOptions options = new ChromeOptions();
options.addArguments("--headless", "--disable-client-certificates");
WebDriver driver = new ChromeDriver(options);

Solution 5: Third-Party Tools (Advanced)

If the above fails, use tools like AutoIT (Windows) or AppleScript (macOS) to interact with system dialogs:

WinWait("Security Information")
ControlClick("Security Information", "", "Button2") ; Clicks "Cancel"

Call this script from Selenium using Runtime.getRuntime().exec("script.exe").

Notes

  • Browser Compatibility: Solutions 1-4 work for Chrome/Firefox. Adjust flags for Edge/Chromium.
  • Security Implications: Disabling certificates may affect HTTPS behavior. Use only in test environments.
  • Logging: Monitor browser logs for certificate-related errors.

By configuring the browser to suppress certificate prompts, you eliminate the need to interact with system dialogs directly.
