firebase phone authorization give admin role

Question

We're using Expo Firebase Phone Authentication. We're able to authenticate users using the firebase sdk, so when a new phone number signs up for the first time, we add that phone number to the Users section of the firebase console. However some of these phone numbers need to be marked as admin. Is there any way to do that from the firebase console?

Answer 1

If you are talking about marking particular users as an admin in the Authorization tabs, then no, this is not currently possible.

If you are looking for ways to do role-based authentication, there are many tutorials available on how to do this. But to summarize, there are three main methods for role-based authentication with Firebase.

	Device (Client SDK)	Server (Admin SDK)	Console	Relative Difficulty
Realtime Database	read/write¹	read/write	read/write	High
Cloud Firestore	read/write¹	read/write	read/write	Low
Token-based	read-only²	read/write	not visible	Medium

¹: Using these methods, another admin could add/remove admins from the client side if desired.

²: While the client SDK can not edit a user's authentication token, you could use a Cloud Function or your own private server to edit a user's token from the client if they have the appropriate permissions.
