I need some help for authenticate my angularJS app and my rest api(WEB API) with external social logins( twitter, facebook, google, etc).
I'm working with Web-api and angularJS app(not spa project from Visual Studio, it's independent).
How I should do it if I want to authenticate via oauth through my backend, but having a confirmation to permission access at frontend?
Something like that but using authentification at my backend https://dev.twitter.com/docs/browser-sign-flow
