### 10.1 用户认证与权限控制

> 开启权限及相关配置请先参考 [权限配置](/versions/1.5/cn/docs/config/config-authentication/) 文档

##### 用户认证与权限控制概述：
HugeGraph 支持多用户认证、以及细粒度的权限访问控制，采用基于“用户 - 用户组 - 操作 - 资源”的 4 层设计，灵活控制用户角色与权限。 
资源描述了图数据库中的数据，比如符合某一类条件的顶点，每一个资源包括 type、label、properties 三个要素，共有 18 种 type、
任意 label、任意 properties 的组合形成的资源，一个资源的内部条件是且关系，多个资源之间的条件是或关系。用户可以属于一个或多个用户组，
每个用户组可以拥有对任意个资源的操作权限，操作类型包括：读、写、删除、执行等种类。HugeGraph 支持动态创建用户、用户组、资源，
支持动态分配或取消权限。初始化数据库时超级管理员用户被创建，后续可通过超级管理员创建各类角色用户，新创建的用户如果被分配足够权限后，可以由其创建或管理更多的用户。

##### 举例说明：
user(name=boss) -belong-> group(name=all) -access(read)-> target(graph=graph1, resource={label: person,
city: Beijing})  
描述：用户'boss'拥有对'graph1'图中北京人的读权限。

##### 接口说明：
用户认证与权限控制接口包括 5 类：UserAPI、GroupAPI、TargetAPI、BelongAPI、AccessAPI。
