TouchID for Sudo

Enable TouchID when using Sudo

Overview

Instead of having to type our password each time we use sudo we can instead use Touch ID on our mac keyboards.

While we can use the /etc/pam.d/sudo file for this, changes will not survive system updates, and if we accidentally mess something up, it's quite a pain to fix it!

Instead, we can

• Copy the file /etc/pam.d/sudo_local.template to /etc/pam.d/sudo_local

• Then remove the # in front of the auth like below

# /etc/pam.d/sudo_local
𝗮𝘂𝘁𝗵    𝘀𝘂𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁   𝗽𝗮𝗺_𝘁𝗶𝗱.𝘀𝗼

Then save, and the next time you run sudo, you'll be prompted for Touch ID instead of your password.
