See this Stackoverflow answer: You have enabled Two phase authentication for your Google account and as a result applications will not be able to login to your Google account using the actual password. Google expects you to generate a application specific password for each application you use (and give it a name) and then use that password to login to your Google account from your application. This allows you to not give your password to third party application when you have 2-step authentication enabled. See here what to do.
