Use Touch ID for sudo on Mac
The landscape of security is changing quite a bit. We've gone from basic username and password to 2FA, facial recognition, fingerprint recognition, and so on. Hell, my Mac unlocks simply when I have my Apple Watch near by. In the end, I probably use the Mac fingerprint key the most.
One functionality that still requires manually typing a password is using sudo from command line. Did you know, however, that you can instead require the fingerprint key instead of typing out your password?
# Open the sudo utility
sudo vi /etc/pam.d/sudo
# Add the following as the first line
auth sufficient pam_tid.so
Whether or not you'd prefer to type it out or simply use the fingerprint is obviously personal preference. Since you expect to be be typing in a command line, moving your finger to touch the key is probably not very efficient. If you do want to use fingerprint, however, here you go!

First you need to make the file writable (it is not by default). And you need to do this after every macOS update, because macOS updates reset the file content.
Nice trick. Unfortunately, on Big Sur, at least, it pops up the touch id alert to use it only when the session is terminated, so it’s not useful.
But it is read-only!
As the co-author of sudo, I am amused :)
No need to make it writable when editing it with vi, you just add a
!to the save and exit command (:wq!) and it will save it corectly – it will even preserve the read only state of the file.Works nicely on Big Sur for me, it pops up the touch id alert, I touch and sudo all the things =)
Is there a way to make sudo work with the Apple Watch as well?
