A solid Firebase Authentication implementation that's production ready and covers the essentials. It handles both client and admin SDK setup, supports the standard auth providers (email/password, Google OAuth, etc.), and comes with no extra dependencies. The setup is straightforward: enable your providers in the Firebase console, drop in the initialization code, and you're authenticating users. With 371 installs and passing all three security audits, it's clearly battle tested. If you're building anything that needs user auth and you're already in the Firebase ecosystem, this gets you up and running without reinventing the wheel.
