Hi Dotan,
My approach would be to store the password in the $_SESSION array, but be
absolutely sure that cookies are used for session authorization, to
prevent session hijacking. The good thing about using $_SESSION is that
the password, hashed or not, would *never* be sent to the user. Only the
session id.
By the way: substr($pre_password[0],0) serves no purpose :)
