# Magic Link
Passwordless sign-in via email magic links
Managed Better Auth is built on [Better Auth](https://www.better-auth.com/) and provides full support for the [Magic Link](https://www.better-auth.com/docs/plugins/magic-link) plugin APIs through the Neon SDK. You do not need to manually install or configure the Better Auth Magic Link plugin.
Magic Link lets users sign in by clicking a link sent to their email. No password is required. The flow works like this:
1. The user enters their email address.
2. Managed Better Auth sends an email containing a unique, time-limited link.
3. The user clicks the link, which verifies the token, creates a session, and redirects them to your app.
## Prerequisites
- A Neon project with **Auth enabled**
- The **Magic Link plugin enabled** (see [Enable Magic Link](/guides/auth-guides-plugins-magic-link#enable-magic-link) below)
## Enable Magic Link
**Console**
1. Open the [Neon Console](https://console.neon.tech).
2. Select your project and go to **Auth** > **Plugins**.
3. Toggle **Magic Link** on.
4. Configure the options:
- **Link Expiration** (5-1440 minutes, default: 5) controls how long a magic link stays valid.
- **Allow New User Registration** controls whether magic links can be used to create new accounts. When off, magic links only work for existing users.
**API**
Send a `PATCH` request to configure the Magic Link plugin. All request body fields are optional; send only the fields you want to change.
```bash
curl -X PATCH \
"https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth/plugins/magic-link" \
-H "Authorization: Bearer $NEON_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"enabled": true,
"expires_in": 5,
"disable_sign_up": false
}'
```
| Field | Type | Default | Description |
| ----------------- | ------- | ------- | ----------------------------------------------------- |
| `enabled` | boolean | `false` | Whether the Magic Link plugin is active |
| `expires_in` | integer | `5` | Minutes before the magic link expires (5-1440) |
| `disable_sign_up` | boolean | `false` | When `true`, magic links only work for existing users |
## Use Magic Link with SDK methods
Build a custom magic link flow using the [Neon SDK](/guides/postgres-reference-javascript-sdk). Call `signIn.magicLink()` with the user's email and a callback URL. Managed Better Auth sends the email and redirects the user to `callbackURL` after they click the link.
```ts filename="src/send-magic-link.ts"
import { authClient } from '@/lib/auth/client';
export async function sendMagicLink(email: string) {
const { error } = await authClient.signIn.magicLink({
email,
callbackURL: '/dashboard',
});
if (error) throw error;
}
```
After calling `signIn.magicLink()`, show the user a "check your email" message. For a complete working example with error handling, resend, and state management, see the [magic link example app](https://github.com/neondatabase/neon-js/tree/main/examples/neon-auth-magic-link-example) in the neon-js repository.
## Use Magic Link with UI components
If you're already using Managed Better Auth UI components, you can enable Magic Link with a single prop instead of building a custom form. Pass the `magicLink` prop to `NeonAuthUIProvider`:
```tsx filename="app/layout.tsx"
'use client';
import { authClient } from '@/lib/auth/client';
import { NeonAuthUIProvider } from '@neondatabase/auth-ui';
import '@neondatabase/auth-ui/css';
import './globals.css';
export default function RootLayout({ children }: Readonly<{ children: React.ReactNode }>) {
return (
{children}
);
}
```
Users can now sign in with a magic link by selecting the option on the sign-in screen and entering their email.
> If you haven't set up Managed Better Auth UI components yet, see the [UI components reference](/guides/auth-reference-ui-components) for setup, or the [Next.js](/guides/auth-quick-start-nextjs-api-only) or [React](/guides/auth-quick-start-react) quick start for building custom forms instead.
## Webhooks
If you subscribe to the `send.magic_link` event, Managed Better Auth skips its built-in email and calls your webhook instead, passing `link_type: "sign-in"` in the payload. Your handler is responsible for delivering the link (for example, via a custom email template or SMS).
See the [Webhooks guide](/guides/auth-guides-webhooks) for configuration details and payload format.
## Email provider configuration
For production environments, we strongly recommend using a dedicated email provider. The default shared SMTP should be used only during development. See the [Email provider configuration guide](/guides/auth-production-checklist#email-provider) for setup instructions.
