Playwright & Chrome: "This browser or app may not be secure"

Question

I'm trying to test in Chrome so I can run Google Lighthouse directly in my test suite. When I try to login I get a page from Google saying "The browser or app may not be secure" after I submit my email address.

I've seen a few other posts with this issue and tried their suggestions but I can't seem to work around it, can't anybody help?

This is how I set up my browser in playwright.config.ts

{
  name: 'Chrome - Desktop',
  use: {
    ...devices['Desktop Chrome'],
    browserType: 'chromium',
    launchOptions: {
      ignoreHTTPSErrors: true,
    },
    chromium: {
      args: ['--disable-blink-features=AutomationControlled'],
    },
  } as LaunchOptions,
},

You must also have a recent user-agent

So, along with the arg --disable-blink-features=AutomationControlled you can add these

const { chromium } = require('playwright');

const browser = await chromium.launch({ 
    headless: false,
    args: [
      '--disable-blink-features=AutomationControlled',
      '--no-sandbox',         // May help in some environments
      '--disable-web-security', // Not recommended for production use
      '--disable-infobars',    // Prevent infobars
      '--disable-extensions',   // Disable extensions
      '--start-maximized',      // Start maximized
      '--window-size=1280,720'  // Set a specific window size
    ]
});

and make sure you set in your context one of the latest user-agent, use the npm package "user-agents" (https://www.npmjs.com/package/user-agents) to generate one that fits the browser and the os that you use

const ua = require('user-agents');

const userAgent = new ua({
  platform: 'MacIntel', // 'Win32', 'Linux ...'
  deviceCategory: 'desktop', // 'mobile', 'tablet'
});

const context = await browser.newContext({
   userAgent: userAgent.toString(),
   viewport: { width: 1280, height: 720 },
   deviceScaleFactor: 1,
});

const page = await context.newPage();

in my case, after updating the user-agent to a newer one it finally worked, even if my ua was not that old
