Selenium Chrome 60 Headless Handle Basic Authentication SAML Dialog over HTTPS

I know this is almost a year old, but this is what ended up working for me in a similar situation. It is true that the authentication pop-up has changed and ChromeDriver doesn’t seem to support it or the http(s)://user:[email protected] scheme anymore, but the work-around that I found here seems to do the trick. It was originally written to authenticate a proxy system, but can be modified to work with any authentication system.

Basically you need to make a chrome extension that handles entering the login details on the page. A chrome extension can be added with ChromeOptions.AddExtension(string FilePath) and an extension is just a zip file with a manifest.json and any code files to do the work. Here are the files you’ll need.

manifest.json

{
    "version": "1.0.0",
    "manifest_version": 2,
    "name": "Chrome Proxy",
    "permissions": [
        "proxy",
        "tabs",
        "unlimitedStorage",
        "storage",
        "<all_urls>",
        "webRequest",
        "webRequestBlocking"
    ],
    "background": {
        "scripts": ["background.js"]
    },
    "minimum_chrome_version":"22.0.0"
}

background.js

function callbackFn(details) {
    return {
        authCredentials: {
            username: "YOUR_PROXY_USERNAME",
            password: "YOUR_PROXY_PASSWORD"
        }
    };
}

chrome.webRequest.onAuthRequired.addListener(
    callbackFn,
    {urls: ["YOUR_WEBSITE_ADDRESS"]},
    ['blocking']
);
