Authentication is a key component of software development.
It helps to protect user data and prevent malicious activities.
Creating a custom authentication system can be a time-consuming task, and this is where NextAuth.js comes in handy.
It provides secure authentication support for applications built with the Next.js framework.
What Is NextAuth.js?
NextAuth.jsis an open-source lightweight library that providesauthentication and authorizationsupport for Next.js applications.
It lets developers quickly and easily set up authentication and authorization for their Next.js apps.
It provides features such as authentication with multiple providers, email, and passwordless authentication.
How Does NextAuth.js Work in Authentication?
NextAuth.js’s authentication solution provides a client-side API that you canintegrate into your Next.js utility.
you could use it to authenticate users with different sign-in providers with whom they have created accounts.
Under the hood, users get redirected to a provider’s sign-in page.
Upon successful authentication, the provider returns session data that contains the user’s payload.
This payload can then authorize access to the system and its resources.

Additionally, the clientMaxAge method has been replaced with refetchInterval.
This will make it easier to fetch the session periodically in the background.
