You don't open the xterm on the remote system, but on your
own local system, which requires no password.

In that xterm, you then use ssh to login on the remote computer,
and that's when you either type a password or rely on the
exchange of ssh keys. Everything in the session that passes
across the network is encrypted by ssh.

If, in that remote shell, you open a graphical program that
wants to display on your screen, it connects to a proxy X server
on the remote machine, which forwards the connection to your
local machine through an encrypted channel provided by the ssh.
This all happens automatically, because ssh sets the variable
DISPLAY on the remote system to a string like localhost:10.0,
rather than the :0 that you normally see on the local system.

Cheers,
David.
