If the user wants to circumvent security measures by storing passwords,
that's their option, but it's the programmer's obligation to keep
his/her app as secure as possible.

While 'remember me' is a popular option, it doesn't mean that the site
is storing your password in a cookie. In applications I create, the
password never 'leaves the database'. When the user submits their
login, I'll check the password against what is in the db (after doing
various encrypt methods on it), and that's as far as it goes. If the
login is successful, and the user has a 'remember me' option, I'll
create a unique hash based on a combination of things (like username,
ip, time, random words, etc.), and store that hash in in a temporay
table (as well as in the cookie). When the user comes back, I'll check
that hash, and if successful I'll delete it, and generate a new one for
next visit. And even this type of 'login' may not give the user full
access to their account, as I may ask for the password again if they
want to update some items.

While it is not absolute that you can't store passwords in a cookie, it
is an absolute that you _shouldn't_
