How to customize login on win10?

Question

Windows

Daughter (3 years old) grabbed a screen addiction. Well, I now put passwords on the lock screens of computers and phones.
I was just thinking: is it possible to do this with benefit? Let at least print (at first) learns.
At this stage, I would like to display the word required to enter the system on the lock screen. And to display the entered password by default. However, I can't find any ready-made solutions.
In general, in the future, I would like to download a custom screensaver in order to throw new tasks to the small one.
So the first question is specific: is it possible to automatically show the entered password on the win10 lock screen (I only found the "hide this button" option)?
And the second one is a little less specific: how to cheaply and angrily hang a die that prevents you from using a computer, say, from python?
