Answer 1

application.conf supports environment variables, e.g. db.default.user=${DB_USER}. You can pass it as a console parameter (which is not safe since it appears in ps), or more safely set it as an environment variable.

On Heroku, set the environment variable via heroku config, e.g. heroku config:add DB_USER=MyDBAdmin.

Locally you can set them via export DB_USER=MyDBAdmin, or add them to your ~/.bash_profile (if you use bash).
