We have an app that uses a Firebase database for users and they can register and log in using the app.

I need a way to get this functionality in the website for the app but the website is a WordPress site and currently has no “user” functionality (no registration, login, dashboard, etc.).

I expected this would be a common use case and there would be a number of simple, widely used plugins to integrate it, but this is not the case.

Does anyone have any experience they can share with how they integrated firebase into a wordpress site, or any advice on how to do it?

Thanks for any help.
