I need to implement login functionality in an Ionic2 app. Goal is to allow various social login providers as well (Google, FB, Twitter). I've done this earlier (Ionic1) in a custom way, but now I prefer a framework that handles the calls for me. It seems there is more than one option:
- Ionic (cloud) auth service
- Auth0
- Firebase
It's quite unclear for me how hey exactly differ and which one should be the preferred choice. I can't find existing articles pointing this out (except for this one). Although I see some of these can even be combined which makes it even more mysterious.
Rather than learning everything about those 3 first to make a fact-based decision, I'd love to hear some experienced opinions. Don't want to start a discussion, just get some facts about features, performance, errorproofness etc.
