I set this up a few years ago and it's been very handy. I can also use my Apple Watch to authenticate certain things on my Mac, so I should try to set this up for sudo. Maybe my Yubikey as well. I use external monitors now and leave my MacBook closed in a dock, so it would be nice if I could use an external fingerprint reader that I plug in via USB. I guess the Yubikey is sort of like this, but it's probably not as secure as using a fingerprint.
