An idea to generate unique passwords for different services is to take
the first N characters of the hash of a string that is the
concatenation of the domain name and a master password.
I have a page on my site that does just that in javascript.
No need to maintain anything.
Frequently used passwords are stored in firefox or occasionally even in
my head.

The equivalent bash command I use for the orgmode list is:

echo -n "<masterpassword>lists.gnu.org" | md5sum | awk '{print substr ($1,0,7)}'
