mail not going using gmail smtp laravel and cakephp

Question

At first, emails were sending but both in cakephp and laravel project, emails stopped going. Now, i am getting error:

Swift_TransportException in AbstractSmtpTransport.php line 383: Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/answer/14257 xn11sm52558396pac.38 - gsmtp"

I had removed 2 step verification, turned on the toggle button of allowing access to less secure apps, also unlocked captcha etc. I had tried every step that I found on google.

public $smtp = array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => 465,
        'username' => 'message@abc.com',
        'password' => '123',
        'transport' => 'Smtp',
        'from' => array('noreply@abc.com' => 'abc'),
        'timeout' => 10,
        'client' => null,
        'log' => true,
        'ssl' => true,
        'sender' => array('noreply@abc.com')
    );

I had put here the dummy credentials
