This article is for those who use "Two Factor Authentication" with G suite account and unable to setup his/her account in Microsoft outlook or Livemail
An App password is a 16-digit passcode that gives an app or device permission to access your Google Account. If you use 2-Step-Verification and are seeing a “password incorrect” error when trying to access your Google Account, an App password may solve the problem. Most of the time, you’ll only have to enter an App password once per app or device, so don’t worry about memorizing it.
Note: If you have iOS 8.3 or greater on your iPhone or OSX 10.10.3 or greater on your Mac, you will no longer have to use App passwords to use 2-Step Verification when using the Gmail or any Google branded Apps from iTunes. Using the Google option on the native iOS mail client also does not require App passwords.
