Which component stores usernames, passwords, or encryption keys?

• A. Credential Management
• B. Password Policies
• C. Hardware Key Manager
• D. Complexity

Answer: (C)

Storing usernames, passwords, and encryption keys requires a dedicated, tamper-resistant storage and processing component that isolates secrets from the rest of the system. A hardware key manager is built to do exactly that: it keeps credentials and cryptographic keys in hardware, protecting them from exposure in memory, logs, or software layers. It can generate keys, securely store them, enforce who can access them, and perform cryptographic operations inside the device, which helps prevent keys from being stolen or misused.

The other terms describe practices or rules rather than a secure storage facility. Credential management covers the overall handling of credentials across systems, not the physical protection of the secrets. Password policies specify how passwords should be created and managed, and complexity refers to an attribute of passwords rather than a storage mechanism. So the hardware key manager best fits the need to securely store usernames, passwords, or encryption keys.
