This is kinda open ended question. Just wanted to get some comments / views / pointers on my situation. Before I start with my question I would like to disclose that I have never worked on backend before.
I am trying to build backend for an iOS app that creates user account based on phone number, take some basic information from user such as first name, last name and address. Based on that information I am planning give custom suggestion of weather / whats around etc.
Now for authentication I am using Digits from twitter (https://docs.fabric.io/ios/digits/index.html). But I am not sure how to do whole user management as such. Example collecting more information assigned to same user who was authenticated using phone number.
I thought of using Google's Firebase and Stormpath for user management but they seem to have there own authentication flow. Is there a way to combine either of these with Digits?
Any comments / pointer will be highly appreciated.
