This example shows how to integrate Authsignal with Next.js in order to implement passwordless login using email magic links and server-side redirects.
The login session is managed using cookies. Session data is encrypted using [@hapi/iron](https://hapi.dev/family/iron).
A live version of this example can be found [here](https://authsignal-next-passwordless-example.vercel.app).

Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:
Deploy it to the cloud with [Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
## Configuration
Log in to the [Authsignal Portal](https://portal.authsignal.com) and [enable email magic links for your tenant](https://portal.authsignal.com/organisations/tenants/authenticators).
Copy the .env.local.example file to .env.local:
```
cp .env.local.example .env.local
```
Set `AUTHSIGNAL_SECRET` as your [Authsignal secret key](https://portal.authsignal.com/organisations/tenants/api).
The `SESSION_TOKEN_SECRET` is used to encrypt the session cookie. Set it to a random string of 32 characters.
