Example use case&#x20;

A FinTech startup, FinSecure, developed a proprietary API for handling sensitive financial transactions and personal data. Given the critical nature of the data involved, FinSecure needed to ensure that only the API's owner (the startup itself) could access and manage the API, thereby eliminating the risk of unauthorized access and potential data breaches.
