about password auth - you're wrong (AFAIK). i even gave a reference in my original post. didn't you bother to check it?
However, all modern sshds (AFAIK, at least OpenSSH) default to (publickey, keyboard-interactive). As the name says, keyboard-interactive sends your keystrokes, one at a time (bar buffering) to the remote server.
This is required, for example, when using PAM, as PAM requires the actual authentication key.
