Also consider the case of connecting to a malicious remote host. Either
a totally illegitimate host where you don't have a known_hosts entry or
fingerprint to check, or where a "good" host has been compromised.

With public keys, your password is not sent to the remote system.

With passwords, a modified sshd could log your password (avoiding any
need to brute-force the hash from the password database).
