Nurgled writes "Danga Interactive, who created LiveJournal and memcached, is working on a new decentralized single-signon system called OpenID. Similar in principle to Six Apart's TypeKey or MSN Passport, OpenID will allow you to assert a single identity to any OpenID-supporting site. The difference here is that there is no central authenticating server: anyone can run one, and Danga's reference implementations will be open-source. The site you are authenticating with never sees your username or password, just a one-time token. You can read the initial announcement on LiveJournal, though some details have changed since that post, so be sure to read the information on the official site."
