Hashing passwords is a safety measure before storing them in a database. It transforms a password into a fixed-length string, appearing random for added security, even if user data is exposed.

In the seed.js file, we utilized a package called bcrypt to hash the user's password before storing it in the database. We will use bcrypt later to compare user-entered passwords with the stored ones.

Back to the Project

To use bcrypt in Next.js Middleware, a separate file named auth.ts is created. It includes the authConfig object.

auth.ts

import NextAuth from 'next-auth';
import { authConfig } from './auth.config';

export const { auth, signIn, signOut } = NextAuth({
  ...authConfig,
});

Creadentials Provider

Providers in NextAuth.js are like different login options, such as Google or GitHub. They offer various ways for users to log in.

In the auth.ts file, we're adding a provider called Credentials. This allows users to log in using a username and password.

auth.ts

import NextAuth from 'next-auth';
import { authConfig } from './auth.config';
import Credentials from 'next-auth/providers/credentials';

export const { auth, signIn, signOut } = NextAuth({
  ...authConfig,
  providers: [Credentials({})],
});
