Cross-Device Account Login Through Intermediary Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience due to repeated login operations and password memorization across multiple devices, as existing systems do not efficiently facilitate seamless account authentication across different devices.
Innovation Solution
A method and system that allows authorization by using another device, enabling streamlined login or registration processes by detecting device compatibility and facilitating automated user authentication through prompt-based authorization requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually log in to the same application on different devices, then account security is maintained through password verification, but user convenience deteriorates due to repeated input and memorization requirements
Solution Approach 1:
The system performs preliminary binding between user accounts and multiple devices beforehand. When a user logs in on one device, the system proactively associates that device with the user's account, enabling automated login on previously bound devices without requiring repeated manual authentication.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where a first device sends authorization requests to a second device, which then communicates with the server to obtain authentication tokens. This intermediary process eliminates the need for users to manually input passwords on each device.
2Productivity
If automated login systems are implemented across multiple devices, then user convenience improves by reducing repeated operations, but system complexity increases due to device binding and authorization management
Solution Approach 1:
The authorization system is segmented into distinct functional modules: device binding management, authorization request handling, token generation, and authentication verification. Each module operates independently, simplifying the overall system architecture while enabling automated login across multiple devices.
3Ease of operation
If device binding is implemented for automated login, then repeated login operations are reduced, but adaptability decreases when users need to use new or different devices
Solution Approach 1:
The device binding system is designed to be dynamic rather than static. Users can add new devices to their account binding at any time, and the system automatically updates the authorized device list. This dynamic adaptation allows users to flexibly manage their devices while maintaining automated login functionality.

AI summary
This application provides a method for performing authorization by using another device, an electronic device, and a system. The method includes: Device A sends first request information to device B in response to detecting an operation that a user performs account login or account registration for a first application by using a second application, where the first request information is used to request the second application on device B to perform authorization for the first application; device B sends first information to the first electronic device based on the first request information, where the first information is to be used by device A to request information about a first account, and the first account is a login account of the second application on device B; device A requests the information about the first account from a server based on the first information; and device A receives the information about the first account that is sent by the server, and performs account login or account registration for the first application based on the information about the first account. The method helps improve convenience of performing account login or account registration by the user.
