// Starting May 30, 2022, Google will no longer support the use of third-party apps or devices 
// which ask you to sign in to your Google Account using only your username and password.

// Instead of authenticating with your GMail username/password, a GMail user can create an App Password
// and then login using their username/app_password.   It's literally the same, except it allows a GMail
// account owner to isolate passwords to specific applications.

// The Gmail account owner would first need to make sure she has 2-Step Verification setup for her account.
// Note: The 2FA verification is not a factor when authenticating with an app password. The 2FA is required
// to setup app passwords in the Google account console.  See Sign in with App Passwords

// After the GMail account owner has setup his app password, he simply uses the app password instead of his GMail account password.
