@foreverguest please add to the description that for authentication users have to use ONLY 16-symbolic password that has been generated for the application instead of google account password.
All this 2-phase auth is confusing.
I considered that i have to enter my Google credentials and after that confirm authentication with generated password.
I'm sure I made this mistake the same way as a lot of other people did and will will do.

The problem solved for me.
