Glue the QR code onto an old boarding pass and keep it in your photo album... then stick a broken yubikey into your grandmothers coffin for plausible deniability. - the latter is a joke ofcourse! :) For plausible deniability it's a lot less controversial to mix a broken yubikey in concrete and cast it as pavement.
