What solution would meet the requirements for managing administrator/root credentials and service accounts effectively?

A privileged access management system is designed specifically to manage, secure, and monitor access to sensitive accounts, such as administrator or root credentials and service accounts. This type of system ensures that only authorized users can access these accounts and uses various methods to safeguard these credentials from unauthorized access or misuse.

Privileged access management systems typically incorporate features like session recording, password rotation, and multi-factor authentication, providing a comprehensive approach to securing elevated access rights. They work to prevent abuse of these powerful accounts, thereby reducing the risk of security incidents related to unauthorized access.

The other options serve different purposes. OAuth 2.0 is primarily an authorization framework used for granting third-party applications limited access to user information without sharing credentials. Secure Enclave refers to a hardware-based security feature that provides a secure area for sensitive data but does not specifically address account management. OpenID Connect is an identity layer on top of OAuth 2.0, used for user authentication and does not focus on managing service accounts or administrative privileges.
