How do I set up authentication in my Next.js app using NextAuth?

To set up authentication in your Next.js app using NextAuth, first install the package with npm or yarn.

What configuration do I need to add to my NextAuth setup?

You'll need to create a [...nextauth].js file in the pages/api/auth directory and configure your providers.

Can you give me an example of a provider configuration?

Sure! For example, for Google, you would add:

providers: [
  Providers.Google({
    clientId: process.env.GOOGLE_CLIENT_ID,
    clientSecret: process.env.GOOGLE_CLIENT_SECRET,
  }),
],

How do I protect my routes after setting up authentication?

You can use the getSession method from NextAuth to check if a user is authenticated before rendering protected pages.
