Login Process Description

The mobile side offers different login processes based on the player's account status.The system automatically identifies the player type and guides the corresponding authentication process.

Player Types and Process Differences

• New Players Using for the First Time Need to complete the full registration and compliance process: Register account → Identity authentication → Compliance certification (including region selection, age confirmation, agreement consent) → Enter the game.

• Players with Valid Login State Upon detecting valid login state information, the system automatically completes identity authentication, allowing players to enter the game without manual operation.

• Players with Expired Login State When a login state expiration is detected, the system requires players to re-authenticate. Once verified, they may enter the game.

New Player Registration Options

New players can choose any of the following ways to complete account registration as needed:

• Email Registration Method Players enter their email address, and the system sends a verification code for email verification.Depending on the game configuration, players need to set a password (manual registration) or complete registration directly (automatic registration).

• Third-Party Social Platform Registration Players can use social accounts such as Google, Apple, Facebook, and LINE for quick registration.The system will redirect to the corresponding platform for authorization. Upon successful authorization, a game account is automatically created.

• Guest Mode Experience Players can choose to enter the game directly as guests, skipping the registration process.Guest accounts within the game will prompt binding to a formal account to prevent data loss.

Login State Management Mechanism

• Login State Preservation After a player successfully logs in, the system encrypts and saves the login state information locally.Upon the next game startup, the system will automatically read and verify this information.

• Validity Period Management The validity period of the login state information is 30 days.During the validity period, players can start the game without re-entering their account password, as the system will automatically complete verification.

• Expiration Handling When login state information surpasses the 30-day validity period, the system will clear local information and require players to re-login to ensure account security.

LI PASS Login

LI PASS Email Account is a brand account under Level Infinite, offering two login process plans:

• Smart Guided Login Process: Automatically guides players based on account status to the corresponding registration or login interface, simplifying player operation.
• Traditional Login Process: Provides separate registration and login entries for precise control of player processes.

Additionally, LI PASS supports Passkey Passwordless Login, allowing players to quickly complete authentication through biometrics (fingerprint, Face ID), enjoying a more secure and convenient login experience.

The business can choose the suitable plan according to its needs.

Passkey Login

note

Passkey features are available in Player Network V1.27 and above, currently supported only on mobile platforms:

• iOS: Supports iOS 17.4 and above
• Android: Supports Android 9.0 and above, requiring Google Play Services 20.33 and later versions

Passkey is a passwordless authentication technology based on the FIDO2/WebAuthn standard.It provides a more secure and convenient authentication method for players through public-private key encryption.Players can log in using biometrics (fingerprint, Face ID) or a device PIN, eliminating the need for traditional passwords, thus reducing account theft risk and enhancing user experience.

Advantages of Passkey:

• More secure: Utilizes asymmetric encryption, with private keys stored only on user devices and not on servers, effectively preventing phishing, credential stuffing, and hacking attacks.
• More convenient: Users can log in directly using fingerprint or Face ID without entering passwords, improving login efficiency.
• Cross-device support: Works with Apple iCloud Keychain and Google Password Manager for seamless login across multiple devices.

Create Passkey

Players can create a Passkey in two ways:

• Guided creation post-registration: After completing LI PASS account registration, if the device supports Passkey, a guided creation window will appear.
• Account center creation: Registered LI PASS users can manually create a Passkey under Account Center > Passkey List. More details at Manage Passkey.

1. Players click Create Passkey to enter the creation process.

2. A system authentication window appears, and players authenticate using fingerprint, Face ID, or device PIN.

3. The device generates a Passkey and saves it to iCloud Keychain (iOS) or Google Password Manager (Android).

4. Once the Passkey is successfully created, the system returns a confirmation message, and the player can use the Passkey to log in immediately.

note

If a device does not support Passkey, the creation option will not be displayed.If players close the Passkey creation popup, they can manually create it in the account center.

Login on This Device

If an iOS device has stored the account's Passkey, the Passkey login will be automatically invoked upon entering the LI PASS login page.If using an Android device, or if the Passkey popup has been manually closed, players can manually trigger login by clicking Passkey.

If the device does not contain the account's Passkey, iOS devices will not trigger Passkey login automatically; players must manually select another login method.

This section uses iOS as an example to illustrate the Passkey login user flow.

1. A Passkey authentication window appears, and players authenticate using fingerprint, Face ID, or device PIN.

2. Upon successful authentication, login is completed automatically, and players enter the game lobby.If authentication fails, the system displays an error message and allows players to retry or choose another login method.

Cross-device Login

If players attempt to use Passkey login on a device without a stored Passkey for LI PASS, cross-device QR code login is triggered.Players can also choose QR code login manually on devices with a stored Passkey.

1. In the Passkey authentication window, players select Log in with another device.

2. A QR code is generated, prompting players to use a device with the stored Passkey to scan.

3. Players use a device with the stored Passkey to scan the QR code, triggering a Passkey authentication window on that device.

4. Players authenticate using fingerprint, Face ID, or device PIN to complete cross-device authorization.

5. The target device receives the authorization information, completes login automatically, and players enter the game.

Third-Party Channel Login

LI PASS encapsulates the logic of accessing mainstream third-party social platforms, providing a unified third-party login experience.Quick authentication supports rapid identity verification and user information extraction, automatically obtaining basic player information like nickname and avatars.Simultaneously unifies the access logic of various channels to reduce integration complexity, allowing game teams to freely configure supported channels and display order.

Currently, LI PASS supports mobile channels including (but not limited to):

• Apple
• Google
• Facebook
• GameCenter
• Discord
• Twitch
• Line
• X
• QQ
• WeChat
• VK

Login Process

Below using Google as an example, explains the player process for third-party channel login:

1. Players click the Google icon and redirect to the Google login page.

   

   If the login interface does not display the required third-party channels, players can click the ... (More) icon to view the complete list of third-party channels supported by the game.

   The icon at the upper right corner of the Google channel in the picture above indicates that the player previously used Google Login, reminding the player to continue using the Google channel for login.

2. Player logs into their Google account and returns to the game.

   

3. Players logging in for the first time need to proceed through the compliance process.

   Players logging into the game for the first time must verify the game terms concerning minors to continue playing.Returning players will directly enter the game.

   

4. Player successfully uses their Google account to enter the game.

Guest Login

Guest login is popular in several markets such as Japan.To enhance the player experience, after using guest login, the player will be guided to link their account to LI PASS in the account center.

Guest accounts are unstable and may lead to the loss of guest account credentials, also inconvenience in searching for accounts and resolving issues with customer service.It is recommended to remind players to bind their guest accounts to LI PASS accounts during subsequent processes.

For technical implementation logic and relevant details regarding guest accounts, please refer to the Guest Channel document.

Login Process

1. Players click the ... (More) icon to view the complete list of supported third-party channels.

   

2. Player clicks Sign in as Guest.

   

3. Players logging into the game for the first time need to pass through the compliance process.

   Players logging into the game for the first time must verify the game terms concerning minors to continue playing.Returning players will directly enter the game.

   

4. Upon successful login, the player enters the game.

Account Binding

When players use guest login, the system will recommend binding their account to LI PASS to prevent loss. When players log in through third-party social channels, they can also bind their account to LI PASS.

The binding relationship exists between the channel and openid, and is internal to the game rather than cross-game.

LI PASS has completed the account binding feature, so no additional operations are needed.

Account Binding Relationship Chart

Binding Rules

• Each game allows multiple channel bindings:
  Players can bind multiple social channels simultaneously, then use any channel to log in to the game, and the system will identify the same OpenID and load the related player data.

• Only one UID is allowed per channel:
  As shown above for the Facebook channel, you must unbind Facebook UID A before you can bind a new Facebook UID B.

• Guest accounts bind other login channels:
  For games allowing guest login, a game OpenID is generated at login, and when players later opt to bind a social account or other channels, the channel ID is linked to this game OpenID, allowing login with the bound channel account thereafter.
