You can't. As long as you use telnet, passwds are flying back and forth in ASCII.
At the very least, install SSH and use keys.

rxtelnet
RXTELNET(1) BSD General Commands Manual RXTELNET(1)
NAME
rxtelnet -- start a telnet and forward X-connections.
SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port]
DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be
able to connect securely to your X server. If port is given, that port will be used instead of the default.
If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding.
The supported options are:
-l Log in on the remote host as user username.
-k Disables keep-alives.
-t Send telnet_args as arguments to telnet.
-x Send xterm_args as arguments to xterm.
-X Send kx_args as arguments to kx.
-w Use term_emulator instead of xterm.
-b Use telnet_program instead of telnet.
-n Do not start any terminal emulator.
-v Be verbose.
EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following.
1. On foo: rxtelnet bar
2. You will get a new window with a telnet to bar. In this window you will be able to start X clients.
