True or false? Private apps were historically used for building integration s in a single account.

In the HubSpot Data Integration certification, this statement is True because private apps are specifically designed for "one-to-one" connections where an integration is built for and used within a single HubSpot portal. Unlike public apps, which use OAuth to allow many different HubSpot customers to install the same tool, a private app generates a unique access token that is only valid for the account in which it was created. Historically, private apps were introduced to replace legacy API keys, providing a more secure way to manage internal integrations and custom scripts while still maintaining the simplicity of a direct, single-account connection.
