google chrome - Sign in to gmail account fails (selenium automation)

Question

I have a Selenium service that has to login to my gmail account as the first step. This functionality was working couple of weeks ago, but suddenly the login starts to fails and i am seeing this Error in browser, tried both in Chrome and Firefox drivers in selenium -

This Error comes after the selenium service inserts the email,password and clicks on the sign in button. A similar error was also reported in Google support Forum here- https://support.google.com/accounts/thread/10916318?hl=en, They said that "Google seems to have introduced automation tools detection on their login flow!" but there is no solution in this thread.

Some Other Details which might be useful-

• I am not able to login manually to Google accounts in the browsers
  opened by Selenium.
• But I am able to login manually to these accounts in the Google Chrome application.

Let me know if you need to take a look at the code, i will post it here. Thanks in Advance!

Edit Adding Sample code to refer.

public void loginGoogleAccount(String emailId, String password) throws Exception {
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--profile-directory=Default");
    options.addArguments("--whitelisted-ips");
    options.addArguments("--start-maximized");
    options.addArguments("--disable-extensions");
    options.addArguments("--disable-plugins-discovery");
    WebDriver webDriver = new ChromeDriver(options);
    webDriver.navigate().to("https://accounts.google.com");
    Thread.sleep(3000);
    try {
        WebElement email = webDriver.findElement(By.xpath("//input[@type='email']"));
        email.sendKeys(emailId);
        Thread.sleep(1000);

        WebElement emailNext = webDriver.findElement(By.id("identifierNext"));
        emailNext.click();
        Thread.sleep(1000);

        WebDriverWait wait = new WebDriverWait(webDriver, 60);
        wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("identifierNext")));

        Thread.sleep(3000);
        WebElement passwordElement = webDriver.findElement(By.xpath("//input[@type='password']"));
        passwordElement.sendKeys(password);

        Thread.sleep(1000);
        WebElement passwordNext = webDriver.findElement(By.id("passwordNext"));
        passwordNext.click();

    } catch (Exception e) {
        LOGGER.info(String.format("No email/password field available or it is already logged in: [%s]: ",
                e.getMessage()));
    }
}

Toggle "Allow Less Secure App Access"
There is a setting on your account that you can toggle that may help with this. It is the "Allow Less Secure App Access". You should be able to visit the link below to toggle that setting if you are already logged into the gmail account you want to modify.

Link to change setting on google account: https://myaccount.google.com/lesssecureapps
