authentication - Is Facebook an OpenID provider?

Question

Is Facebook an OpenID provider? I know they are an OpenID supporter but do they allow people to authenticate with other sites via OpenID with their Facebook credentials?

Answer 1

No, they're not an OpenId provider. They use their own OpenID-like system called Facebook connect, which you can use to authenticate users on your site, among other features.
