Authentication verifies who a user is, while authorization controls what a user can access. Next.js supports multiple authentication patterns and providers.

In this lesson, we’ll look at adding authentication to our Next.js application with NextAuth.js, a full-featured authentication system with built-in providers such as Google, Facebook, or Github. It also supports JWT, email/password, and magic link authentication.

So, we’ll start by creating the corresponding Next.js API routes to allow our users to authenticate using their Google account. We’ll also set up our OAuth client from the Google Cloud console and link everything inside our app.
