The number of providers listed on Spread OpenID is growing even more. We have added StartCom SSL to the provider listing today.
StartCom SSL allows login by client certificates and smart cards. It is a welcome trend that OpenID providers are adding more secure layers to the usual username/password login method to their services. This will hopefully further the acceptance and use of OpenID even more.

Hm, the website of StartCom SSL is available. Don’t know about the provider, though.
