Phone Authentication using firebase

Basic firebase phone verification setup with simple HTML/CSS/JS

Typed React hooks for Firebase — one hook per flow, with its state, errors, and callbacks handled. Each service is its own import, so an app only carries what it uses.

React native login with phone number and email signup with Google Firebase.
