# configurationData

Additional configuration information for the token instance.

## Declaration

```swift
var configurationData: Data? { get set }
```

## Discussion

Discussion configurationData can provide token-implementation-specific additional data, which the app that hosts the token driver extension and configures the token provides. The system doesn’t interpret this data in any way. For example, the network-based hardware security module (HSM) can store encoded target network addresses, access credentials, or the list of identities the HSM contains.
