# Passkey Registration Options

These endpoints power passwordless sign-in (passkeys / WebAuthn) and account recovery (magic links, recovery codes, email verification) for your app's end users. Handles the registration options.

This method is on the runtime **API** surface (`norbix.api.membership`) — call it from your app.

{% hint style="info" %}
These examples assume the SDK is installed and your credentials are set as environment variables — each client reads them automatically, so the constructors below take no arguments. See [Install a Norbix SDK](/sdks-and-cli/install.md).
{% endhint %}

{% tabs %}
{% tab title="JavaScript / TypeScript" %}

```ts
import { Norbix } from '@norbix.ai/ts';
const norbix = new Norbix();

const result = await norbix.api.membership.passkeyRegistrationOptions({
  verificationToken: 'vtok_a1b2c3d4e5',
});
```

{% endtab %}

{% tab title=".NET" %}

```csharp
using Norbix.Sdk;
using Norbix.Sdk.Types.Api;

using var client = new NorbixClient();

var result = await client.Membership.PasskeyRegistrationOptionsAsync(new PasskeyRegistrationOptionsRequest
{
    VerificationToken = "vtok_a1b2c3d4e5",
});
```

{% endtab %}
