HugeGraph 支持通过 RESTful API 创建用户、设置密码，并为指定图分配权限。核心流程如下：
1. **创建用户**
使用 `POST /graphs/{graph}/auth/users`，请求体为 JSON，例如：
```json
{
"user_name": "newuser",
"user_password": "yourpassword",
"user_phone": "1234567890",
"user_email": "[email protected]"
}
```
密码会自动加密存储。接口实现详见
[UserAPI](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/auth/UserAPI.java)。
2. **修改用户密码**
使用 `PUT /graphs/{graph}/auth/users/{id}`，请求体只需包含新密码字段：
```json
{
"user_password": "newpassword"
}
```
详情见 [UserAPI update
方法](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/auth/UserAPI.java)。
3. **分配权限**
需先创建用户组（group）和目标（target），然后通过 `POST /graphs/{graph}/auth/accesses`
分配权限，示例请求体：
```json
{
"group": "groupId",
"target": "targetId",
"access_permission": "READ", // 或 WRITE、ADMIN 等
"access_description": "描述"
}
```
权限类型由 `HugePermission` 枚举定义。接口实现见
[AccessAPI](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/auth/AccessAPI.java)。
4. **认证方式**
默认超级管理员为 `admin`，认证采用 HTTP Basic Auth，格式为 `Authorization: Basic
base64(admin:密码)`，如需示例可参考 [相关
issue](https://github.com/apache/incubator-hugegraph/issues/2727)。
如需更详细的 API 字段说明，可直接参考源码中的 `JsonUser` 和 `JsonAccess` 类定义。实际操作建议用 Postman 或
curl 进行接口调用。
