Which long password? The game account is separate from STEEM blockchain account and you don't need your STEEM keys for login. I've explained the process in the post above.

In short, just like you create any other account websites, you download the app, click on Register button and fill the registration form for the "game" account on our server. There, you mention your correct username and write your game tracking name. After successful registration, you'll have to verify your account. For verification, send 3 STEEM to Hive account@super8ballclub with the game tracking name in the memo field and you'll be verified in the next 24 hours.
