When configuring the database connection, which option exists for storing credentials other than plain text?

Using Hashicorp Vault for storing database credentials provides a robust solution that allows for securing sensitive information without relying on plain text. Hashicorp Vault is designed to manage secrets and protect sensitive data through encryption, access controls, and efficient secret leasing.

When credentials are stored in Hashicorp Vault, they are encrypted and can be accessed securely by applications as needed. This approach minimizes the risk of exposure that comes with plain text storage, allowing organizations to implement fine-grained access policies and audit their secret access.

In contrast, options like database encryption focus more on securing the database itself rather than providing a management solution for secrets, while secure credential storage and encrypted secrets manager are more generic terms that do not specifically reference a well-defined system like Hashicorp Vault. Thus, Hashicorp Vault stands out as a dedicated tool for storing and managing database credentials securely.
