Recently bought a YubiKey 5 to use with my Linux desktop
Now I can automatically decrypt the filesystem just by plugging in the key during boot, and login / sudo just by tapping the button! No more typing passwords, but everything is still encrypted and secure.
A little disappointed that Intel Macs can’t use it with FileVault during boot, but the Mac already has a fingerprint reader so I wasn’t planning to use the YubiKey with it anyway.
