A bit of a nitpick, but I've noticed the trend of several sites to only allow SSO with one, maybe two, 3rd parties. More egregious, no ability to sign up directly.

Are other languages missing something like node's Passport to allow easy integration to multiple SSO providers or is single-single service sign on an active choice that is growing in popularity?

I've read that people think offering to many choices is confusing...

I agree though, unless you directly tie into another service direct sign-up is a must. And I still don't understand why OpenID had to die...

I was actually thinking that is Omniauth enough as a log in option?
