How to Best Store and Access Credentials in Julia?

Usually environment variables are used for this, perhaps with an .env file that you source:

export DB_USER=fredrik
export DB_PASSWORD=*******

and then access as

db_user = ENV["DB_USER"]
db_password = ENV["DB_PASSWORD"]

Edit: Looks like Discourse automatically edits the post and insert *s instead of my password. I typed DB_PASSWORD=hunter2 but it was edited.
