Dreamhost (which is not cPanel-based) announced yesterday that they are adding multi-factor authentication via Google Authenticator as optional for all accounts.
It would be nice if cPanel supported this (Google Authenticator).
cPanel will need to eventually support it - and probably very soon. The concept of multi-factor authentication is rapidly entering public consciousness - YubiKey, Google Apps, even Blizzard's Battle.net now uses multi-factor and "using an authenticator" has entered the common vocabulary.
An option for users to enable multi-factor authentication is a must. I would like to see both Google Authenticator and YubiKey.
