I recently got a pair of yubikeys… they have been around about ten years already and support industry standards. Guess how many services I use support them? A smaller fraction than I’d like.
My employer had a program where you could put in a request and get a free yubikey. Turns out they basically only work with Chrome (no Firefox, no terminal-based auth), so none of my team actually ever uses theirs because it's not really more convenient.
When was that? I use a pair of cheap FIDO2 keys with both Firefox and the Linux PAM module. It's hell of a lot more convenient than typing in passwords to unlock LUKS volumes or sign in to web services, that's for sure. I use mini keys though, they barely stick out of USB ports.
