On Macs with touchbar it can get annoying typing the password everytime you are trying to call "sudo [command] in Terminal.
There is a way to make the touch id scan window appear whenever you are trying to execute a sudo command:
To make this work, just add a line
auth sufficient pam_tid.so
to the beginning of the /etc/pam.d/sudo file.
The file must be edited by the root user, like so:
sudo nano /etc/pam.d/sudo
After making a change, press Control+w, then Control+x and from now on each time you run sudo, you'll be asked to touchid with an oppotunity to opt out to the regular password by pressing a "Use password" button.
Why Apple hasn't set this enabled in default configuration or at least added a checkbox to the UI in System Preferences?
