What is the term used to describe a cloud system that stores, manages, and enables auditing of API keys, passwords, and certificates?

Secrets management services are designed to store confidential information such as API keys, passwords, and certificates. They also offer features to manage, retrieve, and audit these secrets. In contrast, a public key infrastructure (PKI) typically focuses on certificates and encryption keys without including passwords or API keys. A Trusted Platform Module (TPM) is a hardware-based security system, while the term "hush service" is a made-up term for the purpose of this question.
