In this video I demonstrate how I integrated Auth0 with my latest mobile App to include social logins from Facebook, Google, LinkedIn, Twitter as well as a traditional email/password signup form. You can see the functioning App in both App stores at http://www.10xWorking.com
This utility allows you to only have to create an account at Auto0 and from there with some JavaScript (or many other supported languages) you can use all the other social platform logins.
