# React Native Kit

`vida-cdk-react-native` is a React Native Module that wraps functions from iOS and Android SDK libraries (CredentialServicesKit). It allows you to register an unbound VIDA credentialId to a device, generating P256 key pairs for signing message strings with or without user presence. User presence can be authenticated using a password or optionally using biometric authorization if enabled.
