Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.vngcloud.vn/vng-cloud-document/vstorage/object-storage/vstorage-hcm03/identity-and-access-management/managing-vstorage-access-account/service-account.md). # Service Account A Service Account is an identity that you can create within your account with specific permissions. It shares some similarities with IAM User Accounts. Both Service Accounts and IAM User Accounts are identities with policies that determine what the identity can and cannot do with GreenNode resources. However, a Service Account is an identity used by an application or a machine, rather than a human, to execute authorized API calls and access designated resources. For more information about Service Accounts, please refer to . To access and work with vStorage resources using a Service Account, in addition to the Service Account, you need to create **vStorage Credentials**. These credentials consist of S3 keys and Swift user account pairs, which are attached to that Service Account. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.vngcloud.vn/vng-cloud-document/vstorage/object-storage/vstorage-hcm03/identity-and-access-management/managing-vstorage-access-account/service-account.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
