I'm developing an idea and I just started trying out Authentication. All of the other Firebase services I want to use require API key that needs to be added to the site. Specifically, following the Authentication example: it's pasted in the login form itself.
Following the Authentication example, this would be visible when pressing CTRL+U.
When I check the code on a browser, the API key is obviously visible which I think is pretty dangerous. Is there any way to do these kinds of things securely when hosting your app on Firebase Hosting?
