There are several add-on security packages available, but for free you could
try some variety of the following UDC:

mylogonudc
option logon,nobreak,nohelp
if hpldevin=21 then
   setvar myguess ""
   set echo=off
   input myguess; prompt="Enter dialup password: "; wait=60
   set echo=on
   if ups(myguess)<>"MYPASSWORD"
      echo Sorry, bad guess!
      bye
   else
      echo Welcome to !hpsysname!
      endif
   deletevar myguess
   endif
*

First improvement: put it in a command file that your OPTION LOGON UDC
executes.  This makes it easier to update.

Second improvement: add a loop, so the user has more than one chance to enter
the password (if you type as badly as I do).

Third improvement: change the prompt from "Enter dialup password:" to ":", so
the bad guys don't even know a password is required.

Note: make sure the UDC (or command) file are not readable!  The users only
need execute access.

Have fun!
