 ## Initial Users<a name="en-us_topic_0237121100_section41994915210"></a>
 
-The account automatically generated during openGauss installation is called an initial user. An initial user is the system, monitoring, O&M, and security policy administrator who has the highest-level permissions in the system and can perform all operations. The username is the same as the name of the OS user who installs openGauss. The initial password is  **GaussDB@2012**. After the first login, change the initial password in time.

The username is the same as the name of the OS user who installs openGauss，please refer to the *Installation Guide* for detail.
 
 An initial user bypasses all permission checks. You are advised to use an initial user as a database administrator only for database management other than service running.

-openGauss安装过程中自动生成的帐户称为初始用户。初始用户也是系统管理员、监控管理员、运维管理员和安全策略管理员，拥有系统的最高权限，能够执行所有的操作。该帐户与进行openGauss安装的操作系统用户同名，其初始密码为GaussDB@2012。在第一次登录数据库后，请及时修改此初始化密码。
+openGauss安装过程中自动生成的帐户称为初始用户。初始用户也是系统管理员、监控管理员、运维管理员和安全策略管理员，拥有系统的最高权限，能够执行所有的操作。该帐户与进行openGauss安装的操作系统用户同名，具体请参见《安装指南》。
 
 初始用户会绕过所有权限检查。建议仅将此初始用户作为DBA管理用途，而非业务应用。
