Authentication via device ID

Device ID authentication lets users start using the application on a mobile device without entering registration data. The first time a user logs in to the application using the device ID, a new account is created automatically, and the user doesn’t need to enter a username, email address, or other data.

Notice
The account created by the device ID allows using the application only on the current mobile device. Access to it is lost after changing an Android or iOS device or after uninstalling an application on an iOS device. To save progress in the application and use the account on other devices, the user can upgrade the account by linking a social network or by entering a username, email address, and password.

With the device ID, you can implement user authentication on one or more mobile devices in the background mode. To use this function, the user should link the device ID to an existing account.

The SDK supports authentication via ID of mobile devices on Android and iOS.

To enable user authentication via device ID for your project:

  1. Open your project in Publisher Account and go to the Login section.
  2. Click Configure in the pane of a Login project.
  3. In the top settings block on the navigation page, click Login API integration.
  4. Set the Login with device ID toggle to On.
  5. Click Save changes.

Get device ID

The device ID is generated by the platform and is available in applications installed on the mobile device. The SDK gets the ID value via the platform API and uses this value to perform various functions with the Xsolla API.

The iOS device ID is passed in the UIDevice.identifierForVendor property. The Android device ID is passed in the android.provider.Settings.Secure.ANDROID_ID constant.

To determine the ID, connect the native Xsolla SDK for Android or iOS to your project and use getDeviceId method. See StartingScreenManager.onDeviceIdAuthClicked class of the demo as an example.
