Trusted Device Login Credentials for Faster Cross-Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing login methods require users to repeatedly enter credentials on different devices, leading to high operation costs and time consumption.
Innovation Solution
A method and apparatus that utilize a login credential generated after a trust relationship is established between a device and a user account, allowing devices to log in automatically if the credentials match, eliminating the need for manual entry of passwords or verification codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually enter login credentials on each device, then login security is maintained, but operation costs and time consumption increase
Solution Approach 1:
The system performs preliminary actions by establishing trust relationships between devices and user accounts in advance. When a device is first used to login, the system verifies the user's identity through standard authentication and then pre-generates login credentials specific to that device. This preliminary credential generation eliminates the need for repeated manual authentication on the same device, resolving the contradiction between security and operational efficiency.
Solution Approach 2:
The system creates device-specific copies of login credentials based on the original user account authentication. Instead of requiring users to manually enter the same credentials repeatedly, the system generates device-specific credential copies that are automatically validated. This copying mechanism maintains security while dramatically reducing operation costs and login time for subsequent authentications on trusted devices.
2Reliability
If login verification is performed on every device switch, then account security is ensured, but user convenience decreases
Solution Approach 1:
The system applies different authentication qualities to different devices. The first login on a new device undergoes rigorous verification with full security checks, while subsequent logins on the same device use simplified credential validation. This local quality approach ensures account security is maintained for each device while making account switching convenient for users who have already established trust relationships.
Solution Approach 2:
The system performs preliminary security verification when establishing the initial trust relationship between a device and user account. Once this preliminary security check is completed and device-specific credentials are generated, the device is pre-approved for future logins without requiring repeated full verification. This preliminary action ensures security while enabling convenient account switching on trusted devices.
3Reliability
If standard login verification is required for each device, then authentication security is maintained, but operational efficiency decreases
Solution Approach 1:
The authentication process is segmented into two distinct phases: initial device registration with full security verification, and subsequent streamlined logins using device-specific credentials. This segmentation allows the system to maintain high authentication security during the critical first login while achieving high productivity for all subsequent operations on the same device, resolving the contradiction between security and efficiency.
Solution Approach 2:
The system performs preliminary authentication and device verification during the first login, generating device-specific credentials that encode the authentication result. This preliminary action ensures security is established upfront, allowing subsequent logins to proceed with high efficiency by simply validating the pre-generated credentials rather than performing full authentication sequences.

AI summary
Embodiments of this specification disclose a login procedure triggering method, apparatus, and device, and a medium. The solution includes: obtaining a login request that is sent by a first device and that is used to log in to a target application, where the login request includes a first login credential and a first device identifier of the first device; determining a second login credential corresponding to the first device identifier, where the second login credential is a credential that is generated after the first device establishes a trust relationship with a user account of the target application and that is used by the first device to log in to the user account; determining whether the first login credential is consistent with the second login credential, to obtain a first determining result; and if the first determining result indicates that the first login credential is consistent with the second login credential, triggering a procedure of logging in to the target application on the first device by using the user account.
