Intermediate: How to integrate Huawei Auth Service in Unity - Huawei Developers

Introduction
In this article, we will cover how to verify Phone Number and Anonymous Account Login using Huawei Auth Service in Unity Project using Official Plugin (Huawei HMS Core App Services). AppGallery Connect provides a cloud-based Auth Service and SDKs to help you quickly build a secure and reliable user authentication system for your apps to verify user identity.
The AppGallery Connect Auth service supports multiple authentication methods and is seamlessly integrated with other server less services to secure user data based on simple rules that you have defined.
Key Functions​Using the AppGallery Auth Service SDK, you can integrate one or more of the following authentication methods into your app for achieving easy and efficient user registration and sign-in.
Self-owned account: Your self-owned account is used to support the access of your existing authentication system, so that your existing users can access other server less services in a secure manner.
Anonymous account: Anonymous accounts can be used to access your apps as visitors. The Auth service can assign user IDs to your app visitors, so that they can access other server less services in a secure manner. A visitor can be registered as a formal user and retain the original user ID to ensure service continuity.
Third-party accounts: AppGallery Connect allows user identity to be verified by third-party authentication services. The AppGallery Auth Service SDK supports the following accounts for user identity verification:
1. HUAWEI account
2. HUAWEI Game Service account
3. Phone number
4. Email account
5. WeChat account
6. Weibo account
