I can login to my host with my user password.
My user has admin rights.
I can change and delete everything on this computer, why do I have to enter my password twice when I shutdown the host?
If I sit directly at the host/computer I don't have to do that. 
What does this have to do with security at home (local network)?
Is there a possibility to turn this off?
Because you know that no other user has access to this computer and therefore its data can not be destroyed that are not yet saved.

Seems
sudo poweroff
help to 50 % 
For clarification, I've had
systemctl poweroff
used before.
