Sure and pop in whenever I do a git commit? I also sign my commits. I used GPG (different key on the same hardware key) and now via SSH key. I had both a compact and bigger key. I got the compact key because my very first yubikey nearly broke. I lifted my Mac while it was connected and it cracked in the middle. I bought a compact one next which can stay inside and that one you don’t want to take out. It’s so small you’ll lose it. I know because that happened to my backup key … (that was actually the idea for the bigger one I bought but I lost the damn thing during the setup phase)
But having the yubikey bound to your Mac at all times is also stupid because it doesn’t come with a fingerprint or other biometric sensor. The idea is that you use this thing as a token not that you leave the key in the lock at all times. For that alone I would favor the enclave solution.
