Login

Login in authentication is composed of the following steps.

Following image is a flow chart of authentication composed of the steps above.

Refer to the following notes to implement the login function.

Automatic Login

Authentication returns a token key based on login authentication for all users, regardless of IdP type. If this key exists, execute Automatic Login.

Check whether it is possible to automatically sign in by using Automatic Login possibility returned after initializing HIVE SDK or calling isAutoSignIn(). If the value of isAutoSignIn() is true, call signIn() with the parameter, ProviderType.AUTO to carry out Automatic Login.

Followings are sample codes to execute Automatic Login.

Checking Logged-in IdP Account on Device

Automatic Login allows to sign in only with authentication token key of stored PlayerId in the device, so the IdP account of  PlayerID that is logged in may differ from the IdP account that is logged in the actual device. The IdP account logged in on the device is available to check by calling checkProvider(). The IdP account of PlayerID currently logged in is called CurrentPlayer, and the IdP account logged in to the actual device is called DevicePlayer.

When the following conditions are satisfied after Automatic Login, call checkProvider().

    • When the logged in PlayerID is connected with Apple Game Center based on the iOS apps
    • When the logged in PlayerID is connected with Google Play Games based on the Android apps except for the users using Chinese IP

You should compares DevicePlayer and CurrentPlayer returned as a result of checkProvider() in the game and configures the UI for users to choose whether to use the DevicePlayer if DevicePlayer and CurrentPlayer are not matched. If the user chooses DevicePlayer, you must call signOut for CurrentPlayer to log out, and then executes Implicit Login. If the checkProvider () call fails or both accounts are the same, you can stay in auto-login status and enter the game.

Implicit Login

Implicit Login is a method that the user does not select a means of login, but logs in the Apple Game Center account on iOS or the Google Play Games account on Android automatically. Implement Automatic login, and if the automatic login fails, perform Implicit login.

After successful Implicit Login, implement the function to make users go to the game title screen and tap the title to enter the game lobby.

An example screen of Implicit Login

Implement signIn() method with the parameter, ProviderType.APPLE for iOS, and ProviderType.GOOGLE for Android (Google Build) to execute Implicit Login.

Explicit Login

Explicit Login means a process that user chooses an IdP to proceed with authentication. If a player failed to execute both Automatic Login and Implicit Login, implement the game to make the player go to the game title screen and execute Explicit Login when tapping the title.

Explicit Login is composed of the UI provided by HIVE SDK or the UI customized in games with the IdP lists returned after initializing HIVE SDK used in authentication. If you customize the UI, see Advanced > Customizing Explicit Login UI.

HIVE Platform controls and provides IdP lists in accordance with the policy of each country. For example, Google Play Games, Facebook, and Guest Login are not available in China.

To implement Explicit Login with the UI provided by HIVE SDK, you can display the IdP list UI by calling showSignIn() method.

Guest Login

HIVE supports Guest Login to allow users to use the game as a guest without selecting an IdP. You can implement this function for user to choose guest from the Explicit Login UI provided by HIVE SDK, or from the customized UI by game.
Make sure to comply with the following policy when logging in as a guest.

Guest Login Policy
    • Build a game available for both guest users and HIVE members equally.
      Most features of HIVE platform are available for guest users. So, implement your games the same for both guest users and IdP-connected users. For example, guest users are also able to purchase items and pay in the game.
    • Do not allow guest users to sign out.
      If a user logs in as a guest and then logs out, the user can no longer sign in with the same PlayerID. Therefore, do not provide a logout button to prevent users from signing out when their state is the guest.
    • Guest Login Policy with Chinese IP.
      If users access the game with Chinese IP, only authorized members can charge game money or purchase items (started from May 1, 2017). Therefore, IdP lists available with Chinese IP do not include Guest Login.

Implement signIn() method with the parameter, ProviderType.GUEST to execute Guest Login.
Followings are sample codes to execute Guest Login.

Verifying Authentication Token Key

Game server can validate the authentication token key by using the returned token, playerId, and DID information after successful login. HIVE Authentication allows multi-device logins and duplicate connections. Therefore, if the game does not allow duplicate access, you must manage the token key that has been verified or implement the function by managing the session key of the game itself using the token key.

Implement the function by referring to HIVE Server API > Verifying Authentication v4 Token.

Detecting Changes in IdP Account in the Background

Users can change their Apple Game Center or Google Play game accounts through device settings while playing the game. If you need to check whether the IdP account is matched with the account connected with the current PlayerID, implement setProviderChangedListener() after initializing HIVE SDK. If you implement the API, user can receive an event which notifies the changes in IdP account linked on the user device when game resumes.

iOS works when the account in Apple Game Center is changed, and Android works when the account in Google Play Games is changed.  And The response will be delivered only if the currently logged in PlayerID is connected with the relevant IdP. If you receive the change event in IdP account, configure the UI which allows the user to choose whether to use the IdP account logged in on the device. If the user selects the IdP account logged in on the device,  call signOut to sign out and proceed with Implicit Login.

Followings are sample codes to receive events that IdP account setting on device is changed when the player resumes the game.

Logout

If HIVE login is performed, PlayerID and authentication token key are already issued. Logout is responsible for initializing the PlayerID and the token key. If logout is completed by implementing signOut(), move to the game title and execute the Explicit Login when user taps the title.

Followings are sample codes to implement sign-out.
