+# Secure Deletion of User-Created Articles
+
+## Description:
+Enhance the mobile application functionality to now allow users to securely review and delete their own articles. This feature requires the development or enhancement of an OAuth-secured API endpoint that supports deletion operations while ensuring robust security.
+
+## Acceptance Criteria:
+- Users must be able to review and delete only the articles that they have created
+- The system uses OAuth to authenticate users
+- The system verifies that the authenticated user has the appropriate role and permissions to delete the article
+- All deletion operations must be logged with sufficient details
