Security

Some are worrying about easier phishing attacks as the relying party could redirect you to another identity provider than yours.
That's why it's good to have diversity and to have your own identity provider hosted at your own server, with your own style and your own authentication method
If there will be phishing, that will occur for the big OpenID providers
