NoxKey

The tool stores API keys, tokens, and other secrets in the operating system’s keychain, providing a secure local vault that can be accessed programmatically. It offers a simple interface for adding, retrieving, and deleting credentials, and integrates Touch ID authentication to unlock the vault, ensuring that only authorized users can view or use the stored secrets.

Developers and system administrators who need to manage multiple service credentials on a single machine can use it to keep sensitive data out of source code and configuration files. By relying on the native keychain, it leverages existing encryption and access‑control mechanisms without requiring external services.

The project is openly licensed, available at no cost, and is marked as stable, indicating that core functionality is mature and ready for production use.
