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

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $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:
$imap = New-Object Chilkat.Imap

$imap.Ssl = $true
$imap.Port = 993

$success = $imap.Connect("imap.gmail.com")
if ($success -eq $false) {
    $($imap.LastErrorText)
    exit
}

$success = $imap.Login("user@gmail.com","srnyyvqajocnsvdp")
if ($success -eq $false) {
    $($imap.LastErrorText)
    exit
}

$("IMAP Success!")

# For SMTP..

$mailman = New-Object Chilkat.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 -eq $false) {
    $($mailman.LastErrorText)
    exit
}

$success = $mailman.SmtpAuthenticate()
if ($success -eq $false) {
    $($mailman.LastErrorText)
    exit
}

$("SMTP Success!")
