# Example application using [`next-iron-session`](https://github.com/vvo/next-iron-session)

This example creates an authentication system that uses a **signed and encrypted cookie to store session data**. It relies on [`next-iron-session`](https://github.com/vvo/next-iron-session).

It uses current best practices for authentication in the Next.js ecosystem.

**Features:**

- [Static Generation](https://nextjs.org/docs/basic-features/pages#static-generation-recommended) (SG), recommended example
- [Server-side Rendering](https://nextjs.org/docs/basic-features/pages#server-side-rendering) (SSR) example in case you need it
- Logged in status synchronized between browser windows/tabs using **`withUser`** hook and [`swr`](https://swr.now.sh/) module
- Layout based on the user's logged-in/out status
- Session data is signed and encrypted in a cookie
