No. The ssh password is always tunneled, but it's tunnelled "cleartext".
This means that a sysadmin at sveasoft could rig their sshd to capture
the cleartext password to a file, and they could then use it at other
sites where you use the same password.

Note that before you ssh'd in, they don't have your password
unencrypted: they have a password hash.
