Multi-provider authentication on Firestore
I'm working on an MV3 Chrome extension on a feature that requires authentication with a third party provider
Considering that I'm not proficient in backend, I was wondering what's the right way to handle multi-provider authentication, i.e. letting the user to login with both Google and Facebook
FYI, I chose Firebase for several reasons:
1. It has a great integration with extensions such that when I put a listener for a collection on Firestore in the background script, it prevents it from getting terminated
2. Firebase is quite beginner friendly
3. I was recommended for this project to take the NoSQL route
Note that Firebase officially supports authenticating with both Google and Facebook as well as linking accounts (https://firebase.google.com/docs/auth/web/account-linking), however that one works
So far I've successfully managed to store user data with a Google provider, i.e. whenever user completes the Google auth flow, I store his data under the UID I received
I could technically create a lookup collection that maps between users Google UIDs/Facebook UIDs and auto-generated UIDs and then a user's Google/Facebook UID is used to retrieve his data from the users collection, but it would require two reads, and I feel like there is a better and more efficient approach

A friendly place for developers to meet other devs, ask questions, get help, and just have a good time 🙂.
