New solution: One-line install, Homebrew integration, 6718 times smaller in code size

[artginzburg]

TL;DR

As current solution became 5 years old, I propose the following:
github.com/artginzburg/sudo-touchid

Posting here to confirm stability over various systems. Works for me and my friends on macOS Catalina and Big Sur.

It's available through Homebrew. Or without it.
Give it a star if it works for you.

Long story

Solution proposed by @mattrajca is a fork, meaning it needs to be updated along with sudo itself. That's not quite scalable.
Also, the old solution is long. Literally long by meanings of both understanding and installation.

The newly made solution is 6718 times smaller, which means it's so tiny that it could be read by anyone.
It's easily installed without building or using Xcode. This even allows to include it to your automated system build as a one-liner.
It concludes #10, #23, #29, and #30.

What if I don't use Homebrew?

Then you're free to use an installation script utilising only built-in tools, which is also outlined in the repo.

Homebrew provides stability, but is not necessary for the new solution to work.
