As you may be aware, it is possible to use a fingerprint on any Touch ID enabled mac (or Magic Keyboard with Touch ID) to authenticate sudo at the command line. Your mac has been setup to allow you to use Touch ID when you use sudo in Terminal.
This is the prompt you will receive when using
sudo any_command
in Terminal and have at least one fingerprint stored in System Settings / Touch ID & Password.
By pressing your finger on the Touch ID sensor, it will authenticate you to use the command as an admin. You have the option to click “Use Password…” also if you wanted to type your password into Terminal.
