 # Internet Identity Integration
 This sample shows one way to integrate Internet Identity with Android apps. It contains two parts: a dapp with II integrated, and an Unity Project which interacts with this dapp.

 It's an example that integrates with Internet Identity, with the backend and frontend. It derives from the [Internet Identity integration sample](https://github.com/dfinity/examples/tree/master/motoko/internet_identity_integration) demo with some modifications.

 3. Launch the Web Browser from the game to open the dapp frontend deployed in #1, with the public key of `Ed25519Identity` as a parameter.
 4. Login with your Internet Identity in the Web Browser.
 5. Launch the application via App Links, and pass the `DelegationIdentity` back to the game as the URL parameter.
