How can I authenticate a user using Puppeteer?

You can authenticate a user in Puppeteer by navigating to the login page, filling in the credentials, and submitting the form.

Can you provide a code example for that?

Sure! Here's a simple example:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com/login');
  await page.type('#username', 'yourUsername');
  await page.type('#password', 'yourPassword');
  await page.click('#loginButton');
  await page.waitForNavigation();
  console.log('User authenticated!');
  await browser.close();
})();

What if the login requires two-factor authentication?

In that case, you can wait for the 2FA input field to appear and then type the code after receiving it. You might need to use a service to retrieve the code.
