I'm trying to authenticate with the Steam OpenID 2.0 provider on Angular 5, but I found only OpenID Connect libraries, and they do not work with Steam.
Return this error:
Failed to load http://steamcommunity.com/openid/.well-known/openid-configuration: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.
