Secret Manager is a secure and convenient storage system for API keys, passwords, certificates, and other sensitive data. Secret Manager provides a central place and single source of truth to manage, access, and audit secrets across Google Cloud.
You can use Workflows' connector for the Secret Manager API to access Secret Manager within a workflow. This simplifies the integration for you, because the connector handles the formatting of requests, and provides methods and arguments so that you don't need to know the details of the Secret Manager API. The connector also has built-in behavior for handling retries and long-running operations. To learn more about using Workflows connectors, see Understand connectors.
