Everything but employer stuff was cheap on Facebook marketplace. I am a bit on the tail end of my friends and coworkers but not by much. It's always been supremely convenient to be able to choose the form and location of my computing device. The cheap devices are largely disposable - I have several layers of backups. It is this perspective that makes passkeys seem strange, a Cartesian joint of many-to-many between my devices and providers that quickly gets... insane.
(This is in context of Passkeys. If your question is ssh, substantially less:)
But that is the entire premise of Passkeys—they remove the complexity, because having individual passwords per device is clearly superior to user-bound passwords, if you don’t need to worry about it and it just works. Hence why, to stay with SSH, you shouldn’t use SSH keypairs, but certificates signed by a CA.
Imagine having to use a specific password for each service/device combination. Instead we don’t tie passwords to devices, but to users, to avoid this complexity.
