// Set quantity of Hydro tokens to send to the blockchain. Since our token has 18 decimal places, the number that you will need to send may seem large, but remember that the 18 rightmost digits are actually decimals. For example, 313823208533000000 is actually .313823208533000000 Hydro.
challenge.getAmount();
// Randomly generated string used to confirm the validity of the transaction. Only the client requesting the challenge will know the value.
challenge.getChallenge();
// The ID assigned to your firm which will be the same for all authentication requests.
challenge.getPartnerId();

Authenticate authenticate = hydroAuthenticator.authenticate("HYDRO_ADDRESS_ID");
// check is authenticated
authenticate.isAuthenticated();
