Need to prevent OTP message from showing

I believe we still need to cover the path when login credentials are correct, but 2FA isn't required. For this case, we should close the window on success.

Currently implemented and manually tested (automated tests are welcomed here )

* If login credentials are wrong, then redraw the login screen and show error message

* If login credentials are right, then show 2FA screen (unsure about the case when 2FA isn't required.

* If 2FA is wrong, then stay on 2FA screen and show error

* If 2FA is right, then close the auth window

Minimizing calls to  method as it has a lock. Adding padding to make the log file a bit more grokable. Cleaning up some log usages.
