Understanding Supabase Authentication

Introduction to Supabase Auth

Supabase provides powerful authentication capabilities out of the box. This guide will show you how to implement secure user authentication in your Next.js applications.

Setting Up Authentication

First, install the Supabase Auth library:

npm install @supabase/auth-helpers-nextjs

Creating Auth Providers

Email/Password Authentication

const { signUp, signIn } = useAuth();

async function handleSignUp(email, password) {
  const { user, error } = await signUp({
    email,
    password
  });
}

Third-Party Providers

Supabase supports OAuth providers like Google, GitHub, and more:

const { signInWithOAuth } = useAuth();

await signInWithOAuth({ provider: 'google' });
