# Puppeteer

#### What is Puppeteer?

[**Puppeteer**](https://developer.chrome.com/docs/puppeteer/) is a JavaScript library which provides a high-level API to control Chrome or Firefox over the DevTools Protocol or WebDriver BiDi. Puppeteer runs in the headless (no visible UI) by default but can be configured to run in a visible ("headful") browser.

});
  const page = await browser.newPage();
    await page.authenticate({
        username: 'td-customer-USERNAME',
        password: 'PASSWORD'
    });
    await page.goto('https://ipinfo.thordata.com');
