Pre-authenticated requests provide a way to let users access a bucket or an object without having their own credentials. When you create a pre-authenticated request, a unique URL is generated. Anyone you provide this URL to can access the Object Storage resources identified in the pre-authenticated request, using standard HTTP tools like curl and wget. It is recommended that you do not make these PARs publicly accessible, and that you set a short expiration date which matches your data loading plan.
It is recommended to use a resource principal for access to more sensitive data in Object Storage as a resource principal is more secure.
For more information about pre-authenticated requests, see the Oracle Cloud Infrastructure documentation at Using Pre-Authenticated Requests. Also see Securing Object Storage in the Oracle Cloud Infrastructure documentation.
