# IAM User Account

**IAM User Accounts** are representative accounts used to interact with GreenNode through the Portal UI. A user account at VNG includes authentication information (username and password) and is by default set with no access rights. These user accounts do not exist independently; they belong to a single root user account and do not incur any additional fees.

If your business has multiple members who need access to GreenNode, it is recommended not to share the security information of the root user account. VNG encourages you to create user accounts for each member under your root user account, allowing you to assign different permissions to each user account.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

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/iam-user-account.md?ask=<question>&goal=<endgoal>
```

`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.
