An alternative to storing the data in the database (as Qasim answered) is to use the Firebase Admin SDK to look up the user's profile by its UID.

The Firebase Admin SDK runs with administrative privileges, and thus can perform certain sensitive operations that the regular client-side SDKs are not allowed to do. As such, it is meant to be only run in trusted environments, such as your development machine, a server that you control, or Cloud Functions for Firebase. With these last two you could create your own API, that your admin panel then calls. Just be sure to secure the API, because otherwise you're leaking user information.

You can only get the firebase authenticated User info from the current session/user, and if you need to query for it later then you need to save it in your own datastore.

For more details, see this https://www.firebase.com/docs/web/guide/user-auth.html#section-storing

  • you can write a migration script or something like that for existing datastore – Qasim Aug 21 '18 at 07:28
