You do know, that by default Windows is using NTLM authentication for
telnet, don't you? Of course that's not comparable to ssh, but it sure
is a lot better than plaintext authentication.

Thats totally true, but worthless.  Authentication isn't the problem,
it's the transmission that's in the clear, so now you're sending your
loging name and password in cleartext.  Sure, they're stored in NTLMv2
format at the other end, but what does that matter if they just put a
sniffer on the wire?

if you had bothered trying before writing this, then you would know that
this is simply not true.
I fully agree that having the session data unencrypted is bad enough,
but authentication is definitely not using plaintext anywhere.
