Token-Based Third-Party Notification Access Without Credential Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in granting access to first-party applications for multiple third-party applications, and there is a concern about sharing credentials between different application providers, leading to tedious consent processes and potential security issues.
Innovation Solution
A system that allows a client device to provide an access code to third-party applications, enabling them to access a first-party notification interface, which is otherwise restricted, using a refresh and access token obtained from an authentication server, without revealing user credentials, facilitating secure data transfer between linked accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user manually approves each third-party application's access to first-party features, then security is maintained through credential verification, but user convenience deteriorates due to tedious repeated consent processes
Solution Approach 1:
The system performs preliminary authentication by obtaining user credentials once during account setup. This pre-authenticated session is then reused for subsequent third-party application approvals, eliminating the need for repeated manual credential entry and approval processes while maintaining security
Solution Approach 2:
The system enables automatic approval of third-party applications by leveraging the pre-established authenticated session. The authentication mechanism serves itself by reusing the initial credential verification across multiple applications without requiring continuous user intervention, thus improving convenience while preserving security
2Ease of operation
If first-party applications share user credentials with third-party applications, then access control is simplified, but security deteriorates due to exposure of sensitive information
Solution Approach 1:
The system extracts only the necessary authentication information from the user's credentials to generate access tokens for third-party applications. Instead of sharing full credentials, the system derives limited-use tokens that provide just enough access control functionality without exposing sensitive user information
Solution Approach 2:
The system introduces an intermediary authentication mechanism that stands between the user's credentials and third-party applications. This intermediary layer processes credential verification and issues access tokens, preventing direct exposure of sensitive information while maintaining proper access control functionality
3Reliability
If multiple third-party applications require separate credential approvals, then security is maintained through individual verification, but time consumption increases due to repeated approval processes
Solution Approach 1:
The system merges multiple individual approval processes into a single unified authentication event. By combining the credential verification for multiple third-party applications into one initial authentication action, the system maintains individual security verification while dramatically reducing the time users spend on repeated approval processes

AI summary
Implementations disclosed herein provide for a third-party application an ability to access a first-party notification interface without receiving credentials linked to a first-party user account. In addition, a device-level permission is established such that each third-party application operating on a client device does not need to seek permission to access the notification interface. A third-party application may request an access code from a client device. The access code may be presented to an authentication server. The authentication server may provide an access token and a refresh token to the third-party application. The third party application may provide the access token and data to be included in a notification to the first-party notification interface.
