Answer 1

You should create app password in google app password and use that password.

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. source
