“OpenIDs are universal login names
which can be used at any OpenID-
enabled website. These usernames
resemble regular website domains or
addresses, such as example.com/bill
or steve.example.com”

History
• Developed by Brad Fitzpatrick of LiveJournal
• Driven by blogosphere needs
• Bounty program of $50,000 launched in 2006
• ~160 million OpenID’s and ~10 thousand
sites supporting it
“Nobody should own this. Nobody’s planning on making any money from
this. The goal is to release every part of this under the most liberal licenses
possible, so there’s no money or licensing or registering required to play. It
benefits the community as a whole if something like this exists, and we’re all
a part of the community.”
