Amazingly enough, this is covered in the FAQ (perlfaq8, to be
specific; perldoc perlfaq8 on most systems, man perlfaq8 if MANPATH is
How do I ask the user for a password?
(This question has nothing to do with the web. See a
different FAQ for that.)
There's an example of this in the crypt entry in the
perlfunc manpage). First, you put the terminal into "no
echo" mode, then just read the password normally. You may
do this with an old-style ioctl() function, POSIX terminal
control (see the POSIX manpage, and Chapter 7 of the
Camel), or a call to the stty program, with varying
degrees of portability.
You can also do this for most systems using the
Term::ReadKey module from CPAN, which is easier to use and
in theory more portable.
Use the FAQ.

perldoc perltoc is your friend.
