# loginWithOneTimeCode

[API Reference](/api-reference/modelence/client/functions/../../../index) / [modelence](/api-reference/modelence/client/functions/../../index) / [client](/api-reference/modelence/client/functions/../index) / loginWithOneTimeCode

> **loginWithOneTimeCode**(`options`): `Promise`\<`null` | `User`>

Defined in: [packages/modelence/src/auth/client/index.ts:235](https://github.com/modelence/modelence/blob/0db3afaa9e9d0dc8b5bc30d984757f5ba9684f92/packages/modelence/src/auth/client/index.ts#L235)

Complete a magic link sign-in by typing the one-time code from the email.

Alternative to `loginWithMagicLink()` for contexts where clicking the link
can't reach the app — native apps without deep links, or when the email is
read on a different device. Signs the user in — creating the account first
when the email is not registered yet and the server enables
`auth.magicLink.allowSignup` — and returns the logged-in user.

## Example

```ts theme={null}
const user = await loginWithOneTimeCode({ email: 'user@example.com', code: '482193' });
```

## Parameters

| Parameter       | Type                                      | Description                           |
| --------------- | ----------------------------------------- | ------------------------------------- |
| `options`       | \{ `code`: `string`; `email`: `string`; } | -                                     |
| `options.code`  | `string`                                  | The one-time code from the email.     |
| `options.email` | `string`                                  | The email the magic link was sent to. |

## Returns

`Promise`\<`null` | `User`>
