Authentication failure suggests invalid credentials (email id or password). I assume you have verified these. You mention that you are able to login to this account. Is multi-factor authentication setup for this account? That might cause problems too. Adding the debug property may help.

Yes, the issue was multi factor authentication. It is fixed.
