Failed to authenticate on SMTP server with username using Laravel Jetstream

Question

I'm learning how to send email to the user whenever their system role change using Laravel 8 and I had this issue where most tutorials that I'm following requires the Google Account to turn on the Less Secure Apps, but I cannot change the settings in the Google Account anymore it says This setting is no longer available . I am using Laravel and Jetstream. Below is the error I'm getting:

Failed to authenticate on SMTP server with username "myEmail@gmail.com" using the 
following authenticators: "LOGIN", "PLAIN", "XOAUTH2". Authenticator "LOGIN" returned 
"Expected response code "235" but got code "535", with message "535-5.7.8 Username and

Does anyone know how to send emails in laravel or a tutorial on doing it? Thank you.

Follow this to generate new apps password and set your env file like this

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=YOUR_GMAIL@gmail.com
MAIL_PASSWORD=YOUR_GENERATED_PASSWORD 
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS="hello@example.com"
MAIL_FROM_NAME="${APP_NAME}"

make sure your port and encryption setting is also changed in mail.php

        'smtp' => [
        'transport' => 'smtp',
        'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
        'port' => env('MAIL_PORT', 587),
        'encryption' => env('MAIL_ENCRYPTION', 'tls'),
        'username' => env('MAIL_USERNAME'),
        'password' => env('MAIL_PASSWORD'),
        'timeout' => null,
    ],

you probably need to clear cache before test it out

php artisan config:cache
