Demonstrates how to authenticate using an app password with GMail for IMAP and SMTP. B4X

Dim success As Boolean = False

'  This example requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

'  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:
Dim imap As ChilkatImap
imap.Initialize("imap")

imap.Ssl = True
imap.Port = 993

success = imap.Connect("imap.gmail.com")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


success = imap.Login("user@gmail.com", "srnyyvqajocnsvdp")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


Log("IMAP Success!")

'  For SMTP..

Dim mailman As ChilkatMailMan
mailman.Initialize("mailman")

mailman.SmtpHost = "smtp.gmail.com"

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

mailman.SmtpSsl = True
mailman.SmtpPort = 465

success = mailman.SmtpConnect
If success = False Then
    Log(mailman.LastErrorText)
    Return
End If


success = mailman.SmtpAuthenticate
If success = False Then
    Log(mailman.LastErrorText)
    Return
End If


Log("SMTP Success!")
