HarmonyOS NEXT System Account Feature Upgrade: Supports File Encryption Sharing, Application Reinstallation Login Retention

At the Huawei HDC2024 Developer Sub-Conference, the HarmonyOS development team introduced an upgrade to the Huawei account feature in the HarmonyOS NEXT. The enhanced Huawei account will support the use of HarmonyOS devices and native HarmonyOS applications/services, featuring a one-click login capability. Third-party applications will provide a one-click login function without authentication based on the Huawei account mobile number.

According to the introduction, users can log in to applications with one click for the first time, and after the initial login, they can open the application for immediate login, supporting both semi-modal and full-page login styles. The login capability will be opened to third-party applications, starting from NEXT, with each subsequent version system natively defaulting to login, allowing applications to be opened for immediate login, and the login status can be maintained.

Highlights of the Huawei account function on HarmonyOS NEXT are as follows:

Huawei account supports seamless collaborative use across all scenarios, allowing content to be copied and pasted across devices; supports encrypted file sharing, with files only viewable and usable by the shared account user. Additionally, Huawei account supports continuous application functionality, such as seamlessly transferring map information from a phone to a vehicle system in navigation scenarios.

The Huawei account login method has been expanded, allowing users to choose the login method based on the usage scenario, including facial recognition, fingerprint, QR code scanning, mobile number verification code, etc.

Huawei account supports two-factor authentication, combining multiple protection mechanisms, including device certificates based on chip, end-cloud signature negotiation and verification, risk control for sensitive user login operations, etc.

At the same time, this function provides subscription to account abnormal event notifications, with event information proactively pushed to the user.

In terms of login, users can complete the login and mobile number authorization in one step, with consistent experience across all scenarios on mobile phones and tablets, and no need to turn on data traffic. Third-party applications can integrate the login panel function to save development time, and the login panel supports customization.

After users log into an application, the application will maintain the login status. When users uninstall and reinstall the application or switch to a new device, the application will also maintain the login status without the need to log in again.

In compliance with privacy protection requirements, applications will request user information authorization on demand, including user avatar nickname, mobile number, invoice address, invoice header, delivery address, health data, etc.

The Huawei HarmonyOS NEXT system will open various identity verification methods for applications to confirm the identity of the operator, including facial recognition, fingerprint, SMS verification code, etc.

The Huawei account authorization function supports one-time development through system API to achieve consistent experience across multiple devices; the function is integrated without SDK, reducing package size by approximately 900KB, and improving development efficiency. Developers can either reuse the packaged panel or flexibly use buttons according to their own style.
