NextAuth.js
NextAuth.js is a tool to add authentication to our application easily. It handles the complexity of managing user sessions, sign-in, sign-out, and other authentication tasks. Instead of manually building these features, which can be time-consuming and prone to errors, NextAuth.js streamlines the process, offering a unified solution for authentication in Next.js applications.
