' 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.

' For example:
set imap = CreateObject("Chilkat.Imap")

imap.Ssl = 1
imap.Port = 993

success = imap.Connect("imap.gmail.com")
If (success = 0) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

success = imap.Login("user@gmail.com","srnyyvqajocnsvdp")
If (success = 0) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("IMAP Success!")

' For SMTP..

set mailman = CreateObject("Chilkat.MailMan")

mailman.SmtpHost = "smtp.gmail.com"

mailman.SmtpUsername = "user@gmail.com"
mailman.SmtpPassword = "srnyyvqajocnsvdp"

mailman.SmtpSsl = 1
mailman.SmtpPort = 465

success = mailman.SmtpConnect()
If (success = 0) Then
    outFile.WriteLine(mailman.LastErrorText)
    WScript.Quit
End If

success = mailman.SmtpAuthenticate()
If (success = 0) Then
    outFile.WriteLine(mailman.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("SMTP Success!")

outFile.Close
