You can do it quite easily from within your autoexec.bat file, I know because
I have done it.  The password program I created returns a different error 
levels for each user so I can talyor the personality files for games.
The last line at the end of your autoexec.bat should be the name of a 
loop-back file. The loop back file then contains the following lines:

:BEGIN
COMMAND /C CHCKPASS
IF EXIST BADPASS GOTO BEGIN
REN GOODPASS BADPASS

CHCKPASS is a batch file containing the following lines:

PASSWORD
IF ERRORLEVEL 1 REN BADPASS GOODPASS

All that is necessary is that if a valid password is accepted the program 
returns an error level.  BADPASS/GOODPASS is a dummy file that is used as
a semaphore.  If an attempt is made to break out of the password program
the break condition causes the batch file to shell out of command.com back
into the original loop back batch file.  The only other thing is BREAK and
ECHO must be off while attempting this or they can shell out of the loop
back file.
