Cross-Platform Passkey Sync for Unified Credential Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current passkey management systems are limited to individual platforms, requiring re-registration and separate management interfaces, making it inconvenient to use passkeys across multiple platforms and lacking integrated management functionality.
Innovation Solution
A passkey management method and apparatus that enables passkeys generated on one platform to be used across multiple platforms without re-registration, providing integrated management through a single screen, and allowing synchronized or desynchronized passkey status visibility and management across different operating systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passkey management is implemented separately on each platform, then platform-specific security and control are improved, but cross-platform usability and user convenience deteriorate
Solution Approach 1:
The system divides passkey management into platform-specific modules (Windows passkey manager, Android passkey manager, iOS passkey manager) that each handle local passkey operations independently, while a cloud-based passkey synchronization service coordinates between platforms. This segmentation allows each platform to maintain its own security standards while enabling cross-platform functionality through the cloud intermediary.
2Adaptability or versatility
If separate management screens are provided for each platform, then platform-specific control is improved, but system complexity and user learning curve increase
Solution Approach 1:
The passkey agent is designed with universal functionality that operates across multiple platforms (Windows, Android, iOS) with a consistent user interface and feature set. The agent provides unified passkey generation, storage, and management capabilities on each platform, reducing the need for users to learn different interfaces while maintaining platform-specific adaptability through the underlying operating system integrations.
3Reliability
If passkeys are registered individually on each platform, then platform-specific authentication reliability is improved, but time consumption and operational overhead increase
Solution Approach 1:
The system performs preliminary passkey registration on one platform, then automatically synchronizes the passkey to other platforms through the cloud-based passkey synchronization service. This preliminary action eliminates the need for users to manually re-register passkeys on each platform, as the synchronization service proactively distributes the passkey information across all registered devices, maintaining authentication reliability while reducing user time investment.
4Ease of operation
If passkey synchronization across platforms is enabled, then cross-platform usability is improved, but security risks and system complexity increase
Solution Approach 1:
A cloud-based passkey synchronization service acts as an intermediary between different platform-specific passkey managers. This intermediary securely transmits passkey information between platforms using encrypted communication channels, enabling cross-platform usability while maintaining security through the mediation layer that handles authentication and data protection protocols.
Data Source
AI summary
The present disclosure according to at least one embodiment provides a passkey management method for a multi-platform environment, the method being performed by a computing device. The method comprises in response to receipt of a passkey generation request from a passkey agent installed on a first terminal based on a first platform, generating a first passkey usable on multiple platforms, and transmitting the first passkey to the first terminal, in response to receipt of a passkey list request from a passkey agent installed on a second terminal based on a second platform, different from the first platform, providing information regarding a registered passkey list to the second terminal, and in response to receipt of a request for the first passkey, among passkeys included in the registered passkey list, from the passkey agent of the second terminal, transmitting the first passkey to the second terminal.
