All installations via Homebrew are filed independently in the filing system in /usr/local/Cellar and linked into /usr/local/bin which is a directory which allows you to run these commands and apps as if part of the regular operating system.

This directory is also out of the SIP bounds so there should be no authentication macOS error dialog boxes.

HomeBrew is a great package manager just start installing some apps and explore.!
