App got rejected because only using Facebook as login option?
Respond to the reviewer explaining that, providing steps on how to do it. It's possible that functionality was just overlooked.
My app got rejected because lacking significant account-specific functionality from Google
Using firebase is perfectly fine in iOS.
- 1.1 LEGAL: PRIVACY - DATA COLLECTION AND STORAGE - significant account-based features
Read section ii) https://developer.apple.com/app-store/review/guidelines/#data-collection-and-storage
If your core app functionality is not related to a specific social
network (e.g. Facebook, WeChat, Weibo, Twitter, etc.), you must
provide access without a login or via another mechanism.
Since your app is not using any specific social network feature ( facebook,twitter - which demands a login ) you must allow users to provide functionality without login.
You might want to appeal to Appeal board with explanation why user must login in order to use the app ( give examples and screenshots of specific functionality which cannot be used without login ).
If your appeal is rejected you don't have any option but to redesign the app to follow what apple is suggesting. What we have done in past is provide a basic flow without login but once it reaches point where login is must we force user to login ( something like anonymous user).
