Using next firebase auth along side separate backend

[vpaladino778]

Anyone have any experience using this package while not having your backend in nextJS?

I opted to build out a java/Spring backend and use nextJS for the majority of my frontend. I have been trying to consider authentication and the best way to handle it. I already have this package on my app and would like to continue to leverage it if possible.

Anyone have any experience setting this up? Is there a token i should be passing to my backend? Do i need to built a separate /login route on my java backend? Any advice would be appreciated!
