Problem was—as TechCrunch noted—only two OpenID relying parties were allowed to play:
Over 16 months after first declaring its support for the OpenID authentication platform, Microsoft has finally implemented it for the first time, allowing for OpenID logins on its Health Vault medical site. Unfortunately, Health Vault will only support authentication from two OpenID providers: Trustbearer and Verisign. Whatever happened to the Open in OpenID?
But now, Microsoft has decided to increase the number of relying parties by 50%. To three.
A number of folks—me among them—are surprised it’s taken Microsoft this long to add another relying party. And it seems like the list is still missing a few other obvious and highly secure choices.
But myOpenID is a great place to start:
JanRain’s myOpenID service, the first and most popular independent OpenID service on the Internet, provides consumers with a free, fully featured, reliable, and secure solution for managing their personal online identity. Every myOpenID user receives several choices for secure authentication beyond password. These enhanced security options include: Microsoft InfoCard, Client Certificate, or Phone-based two factor authentication.
