Firebase Authentication Patterns

Overview

Firebase Authentication provides backend services for authenticating users with email/password, OAuth providers (Google, GitHub, etc.), and anonymous authentication.

Authentication Providers

Email/Password Authentication

Sign Up:

import { createUserWithEmailAndPassword } from 'firebase/auth';
import { auth } from '@/lib/firebase/client';

export async function signUp(email: string, password: string, displayName: string) {
  try {
    const userCredential = await createUserWithEmailAndPassword(auth, email, password);
