property of a class is better to be desinged as normal method

[zillionare]

some of Security's method, like display_name, it's better to be desinged as property and as a normal method( rather than coroutine function), though Python doesn't permit such behaviour.

To do this, get display_name, alias, code and etc from memory. And if user has to get past information with date, let them get the info by info method
