Intermediate: How to Verify Phone Number and Anonymous Account Login using Huawei Auth Service-AGC in Unity

[shikkerimath]

Introduction

In this article, we will looking that how Huawei Auth Service-AGC provides secure and reliable user authentication system to your application. However building such systems is very difficult process, using Huawei Auth Service SDK only need to access Auth Service capabilities without implementing on the cloud.

Here I am covering sign in anonymously which is anonymous account sign to access your app as guest when you wish to login anonymously, Auth Service provides you unique id to uniquely identify user. And authenticating mobile number by verifying through OTP.

Overview

You need to install Unity software and I assume that you have prior

knowledge about the unity and C#.

Hardware Requirements

• A computer (desktop or laptop) running Windows 10.
• A Huawei phone (with the USB cable), which is used for debugging.

Software Requirements

• Java JDK 1.7 or later.
• Unity software installed.
• Visual Studio/Code installed.
• HMS Core (APK) 4.X or later.

Integration Preparations

1. Create a project in AppGallery Connect.

2. Create Unity project.

3. Huawei HMS AGC Services to project.

4. Download and save the configuration file.

Add the agconnect-services.json file following directory Assests > Plugins > Android

5. Add the following plugin and dependencies in LaucherTemplate.

apply plugin: 'com.huawei.agconnect'

6. Add the following dependencies in MainTemplate.

apply plugin: 'com.huawei.agconnect'


implementation 'com.huawei.agconnect:agconnect-auth:1.4.2.301'
implementation 'com.huawei.hms:base:5.2.0.300'
implementation 'com.huawei.hms:hwid:5.2.0.300'

7. Add dependencies in build script repositories and all project repositories & class path in BaseProjectTemplate.

maven { url 'https://developer.huawei.com/repo/' }

8. Create Empty Game object rename to GameManager, UI canvas input text fields and buttons and assign onclick events to respective components as shown below.

    }
    public void onClickButton(){
        phone = inputFieldPhone.text;
        using (AndroidJavaClass javaClass = new AndroidJavaClass("com.huawei.AuthServiceDemo22.MainActivity"))

Tips and Tricks

• Add agconnect-services.json file without fail.
• Make sure dependencies added in build files.
• Make sure that you enabled the Auth Service in AG-Console.
• Make sure that you enabled the Authentication mode in Auth Service.

Conclusion

We have learnt integration of Huawei Auth Service-AGC anonymous account login and mobile number verification through OTP in Unity Game development. Conclusion is Auth Service provides secure and reliable user authentication system to your application.
