How to do Firebase Facebook Authentication?

I’ve been trying to follow the guides on the Firebase website in order to get Facebook Authentication to work but I just don’t understand how that is suppose to work.
It seems like they want to connect to Facebook from some kind of native process and then use that in Unity. But I can’t just do it from within the engine.

This is the instruction set from the website:

But it seems like the Firebase answer to this questions is: First Authenticate from the native level and then use that in Unity.

What?!

Hi Sabre-Runner,

Year, you need to handle the login yourself :confused:
You need to add the Unity Facebook SDK and login through that. You can find the newest one here.

The SDK contains some very good examples, including how to login.

Good luck,
