# CrossmintPasskeySignerFactory

> Flutter Abstract Interface Class

**Abstract Interface Class**

Experimental factory for creating a passkey signer config.

```dart theme={null}
abstract interface class CrossmintPasskeySignerFactory
```

The default implementation uses the `permissionless_passkeys` package and
is intentionally small so it can be replaced in tests.

## Methods

### createPasskeySigner

```dart theme={null}
Future<CrossmintPasskeySignerConfig> createPasskeySigner({
  required String name,
  required CrossmintPasskeyConfig config,
})
```
