There is still one issue left with Yubikeys: backups. When I loose my Yubikey after I cautiously registered it with a hundred different sites and servers, I would like to restore its secrets onto a brand new (blank) Yubikey and go forward. The only official course of action given by Yubico today is to manually un-register and re-register on all sites and servers.

Of course the key backup should be correctly protected, but that problem is not hard to solve.
