To implement authentication with Next.js, you can use the next-auth library, which supports various authentication providers, including third-party social sign-ins like "Sign in with Google." Here's a general outline of the steps you need to follow:

1. Install next-auth and the required provider packages.
2. Set up your authentication provider (e.g., Google, GitHub, etc.) and obtain the necessary credentials (client ID and secret).
3. Create a [...nextauth].ts file in the pages/api/auth directory of your Next.js project.
4. Configure the authentication provider and other options in the [...nextauth].ts file.

Here's an example of setting up GitHub authentication with next-auth:

1. Install the required packages:

npm install next-auth
npm install @next-auth/prisma-adapter

2. Set up your GitHub OAuth application and obtain the client ID and secret. You can follow the instructions in this extract (https://vercel.com/templates/next.js/roadmap-voting-starter-kit).

3. Create a [...nextauth].ts file in the pages/api/auth directory and add the following code:

// pages/api/auth/[...nextauth].ts
import { NextApiHandler } from 'next';
import NextAuth from 'next-auth';
import { PrismaAdapter } from '@next-auth/prisma-adapter';
import GitHubProvider from 'next-auth/providers/github';
import prisma from '../../../lib/prisma';

const authHandler: NextApiHandler = (req, res) => NextAuth(req, res, options);
export default authHandler;

const options = {
  providers: [
    GitHubProvider({
      clientId: process.env.GITHUB_ID,
      clientSecret: process.env.GITHUB_SECRET,
    }),
  ],
  adapter: PrismaAdapter(prisma),
  secret: process.env.SECRET,
};

4. Add the necessary environment variables (e.g., GITHUB_ID, GITHUB_SECRET, and SECRET) to your .env file.

For other authentication providers, you can check the examples folder (https://github.com/vercel/next.js/tree/canary/examples) in the Next.js repository. Some popular providers include:

• Auth0 (https://github.com/vercel/next.js/tree/canary/examples/auth0)
• Firebase (https://github.com/vercel/next.js/tree/canary/examples/with-firebase-authentication)
• Supabase (https://github.com/vercel/next.js/tree/canary/examples/with-supabase-auth-realtime-db)

Remember to follow the specific setup instructions for each provider.

@charred python I need to do role and group based authentication. How can I do that?

Let me check the knowledge base for you. One moment! :books:

Hmm, I don't know enough to give you a confident answer yet. However, you can refer to the Next.js documentation on authentication (https://nextjs.org/docs/authentication) and explore the various authentication providers mentioned in the examples folder (https://github.com/vercel/next.js/tree/canary/examples) to see if they support role and group-based authentication.
