<Sysname> system-view

[Sysname] line console 0

[Sysname-line-console0] authentication-mode password

[Sysname-line-console0] set authentication password simple 123456

(4)     保存新配置。

(1)     系统出现如下提示信息，表明已经设置成功。

Setting...Done.

(2)     当再次出现BootWare主菜单时，选择<1>，设备开始启动。

(3)     重启设备后设备恢复出厂配置，在系统视图下可以设置新的Console口密码或Super Password，具体方法请参见3. (4)。

(4)     保存新配置。

[Sysname] save

2、通过命令行恢复Console口登录认证密码

通过Telnet或SSH登录设备修改Console口密码

如果用户可以通过Telnet或SSH方式登录设备，并且具有network-admin或者level-15的用户角色，则可以通过Telnet或SSH登录到设备后修改Console口密码，然后保存配置。以下步骤以Telnet为例。

(1)     使用具有network-admin或者level-15的Telnet账号登录设备。

(2)     修改Console用户的密码，修改为密码认证，密码为“admin”为例。

<H3C> system-view

[H3C] line console 0

[H3C-line-console0] authentication-mode password

[H3C-line-console0] set authentication password simple admin

[H3C-line-console0] return

(3)     为了防止重启后配置丢失，执行save命令保存配置。
