GMail App Password

See more GMail SMTP/IMAP/POP Examples

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

require 'chilkat'

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 = Chilkat::CkImap.new()

imap.put_Ssl(true)
imap.put_Port(993)

success = imap.Connect("imap.gmail.com")
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

success = imap.Login("user@gmail.com","srnyyvqajocnsvdp")
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end

print "IMAP Success!" + "\n";

# For SMTP..

mailman = Chilkat::CkMailMan.new()

mailman.put_SmtpHost("smtp.gmail.com")

mailman.put_SmtpUsername("user@gmail.com")
mailman.put_SmtpPassword("srnyyvqajocnsvdp")

mailman.put_SmtpSsl(true)
mailman.put_SmtpPort(465)

success = mailman.SmtpConnect()
if (success == false)
    print mailman.lastErrorText() + "\n";
    exit
end

success = mailman.SmtpAuthenticate()
if (success == false)
    print mailman.lastErrorText() + "\n";
    exit
end

print "SMTP Success!" + "\n";
