With SSH proxy support you normally do _not_ send passwords unencrypted.

Manual SSH proxy tunnel:
ssh -l<proxy-user> <proxy-host> -L  
127.0.0.1:<some-local-port>:<ip-or-host-behind-proxy>:<ssh-port-on-remote-host>

and then an X2Go session to

Hostname: 127.0.0.1
Port: <some-local-port>
User: <ssh-user-on-remote-host>

Both SSH authentications do not reveal clear text credentials. So, I  
am wondering what your SSH proxy strategy will be(?).

Greets,
Mike
