I'd probably go for a $50 Yubikey over a $100 Touch ID upgrade.

Honestly, I don't see it. Are you gonna stay at home with yubikey plugged in? On your couch, in your bed, etc.? It's a matter of months, if not weeks, before you break it? And also need to remember to remove, because otherwise what's the point?

Used to own Yubikey before fingerprint scanners were a thing. I don't see the appeal now, to be honest. I considered it now that I use Asahi on my M1 with no support for TouchID, but still just type in the password because I couldn't be bothered with Yubikey.

Or I'm missing something?
