A lot of sites these days also have password recovery questions.
Since these are actually just additional (usually weak) passwords,
I set them all to randomly-generated password strings as well.  I
would like to store those strings alongside the password.

Right now, there is no structure to the context, so there's no way
to indicate that I have multiple separate "passwords" for the same
context with different subcontexts (which in this case would be the
recovery question).

There also isn't a place to store the username for the site separate
from the overall context.  I use different usernames with different
sites and need to record that somewhere, and for some sites I use a
completely random username as a level of additional security.

It would be nice to be able to add a bit of hierarchical context so
that I can store and retrieve that additional information.
