How to handle login pop up window using Selenium WebDriver?

Now in 2020 Selenium 4 supports authenticating using Basic and Digest auth . Its using the CDP and currently only supports chromium-derived browsers

Example :

Java Example :

    Webdriver driver = new ChromeDriver();
    
    ((HasAuthentication) driver).register(UsernameAndPassword.of("username", "pass"));

    driver.get("http://sitewithauth");
    
 

Note : In Alpha-7 there is bug where it send username for both user/password. Need to wait for next release of selenium version as fix is available in trunk https://github.com/SeleniumHQ/selenium/commit/4917444886ba16a033a81a2a9676c9267c472894

The easiest way to handle the Authentication Pop up is to enter the Credentials in Url Itself. For Example, I have Credentials like Username: admin and Password: admin:

WebDriver driver = new ChromeDriver();
driver.get("https://admin:admin@your website url");

This is a solution for Python based selenium, after going through the source code (here). I found this 3 steps as useful.

obj = driver.switch_to.alert
obj.send_keys(keysToSend="username\ue004password")
obj.accept()

Here \ue004 is the value for TAB which you can find in Keys class in the source code.

I guess the same approach can be used in JAVA as well but not sure.

My usecase is:

1. Navigate to webapp.
2. Webapp detects I am not logged in, and redirects to an SSO site - different server!
3. SSO site (maybe on Jenkins) detects I am not logged into AD, and shows a login popup.
4. After you enter credentials, you are redirected back to webapp.

I am on later versions of Selenium 3, and the login popup is not detected with driver.switchTo().alert(); - results in NoAlertPresentException.

Just providing username:password in the URL is not propagated from step 1 to 2 above.

My workaround:

import org.apache.http.client.utils.URIBuilder;

driver.get(...webapp_location...);
wait.until(ExpectedConditions.urlContains(...sso_server...));

URIBuilder uri = null;
try {
    uri = new URIBuilder(driver.getCurrentUrl());
} catch (URISyntaxException ex) {
    ex.printStackTrace();
}
uri.setUserInfo(username, password);
driver.navigate().to(uri.toString());

Simply switch to alert and use authenticateUsing to set usename and password and then comeback to parent window

Alert Windowalert = driver.switchTo().alert() ;
Windowalert.authenticateUsing(new UserAndPassword(_user_name,_password));
driver.switchTo().defaultContent() ; 

1 way to handle this you can provide login details with url. e.g. if your url is "http://localhost:4040" and it's asking "Username" and "Password" on alert prompt message then you can pass baseurl as "http://username:password@localhost:4040". Hope it works

In C# Selenium Web Driver I have managed to get it working with the following code:

var alert = TestDriver.SwitchTo().Alert();
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthUser + Keys.Tab + CurrentTestingConfiguration.Configuration.BasicAuthPassword);
alert.Accept();

Although it seems similar, the following did not work with Firefox (Keys.Tab resets all the form and the password will be written within the user field):

alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthUser);
alert.SendKeys(Keys.Tab);
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthPassword);

Also, I have tried the following solution which resulted in exception:

var alert = TestDriver.SwitchTo().Alert();
alert.SetAuthenticationCredentials(
   CurrentTestingConfiguration.Configuration.BasicAuthUser,
   CurrentTestingConfiguration.Configuration.BasicAuthPassword);

System.NotImplementedException: 'POST /session/38146c7c-cd1a-42d8-9aa7-1ac6837e64f6/alert/credentials did not match a known command'

Types of popups are defined in webdriver alerts: https://www.selenium.dev/documentation/webdriver/browser/alerts/

Here it is another type - authentication popup - eg generated by Weblogic and not seen by Selenium.

Being HTTPS the user/pass can't be put directly in the URL.

The solution is to create a browser extension: packed or unpacked.

Here is the code for unpacked and the packing procedure: https://qatestautomation.com/2019/11/11/handle-authentication-popup-in-chrome-with-selenium-webdriver-using-java/

In manifest.json instead of “https://ReplaceYourCompanyUrl“ put “<all_urls>”. Unpacked can be used directly in Selenium:

#python:
co=webdriver.ChromeOptions()
co.add_argument("load-extension=ExtensionFolder")

<all_urls> is a match pattern

The flow for requests is in https://developer.chrome.com/docs/extensions/reference/webRequest/
