"'Identity Management' for the Internet is a long-unrealized
dream; a centralized magic single sign-on for the whole Internet.
The idea is to spare us Web surfers from the hassles of managing
multiple logins, and instead have a single universal logon verified

written record of all of my different online accounts, from
shopping sites to online forums, and it contains over 100 different
