How does your login work? What does the class store in order to validate
login? Nowadays, this is typically an authentication token obtained with
OAuth2, or the like. So, you could pass lgn.token to other functions that
need authenticated services, though that is not very different from passing
lgn itself.

What is your objection to passing the login class instance? Alternatively,
all services needing authentication could be part of a single class, where
login() is a class method or derived from a base class.
