4. Configure the basic information.

   Table 1 Parameter for password change rules

   Parameter	Description
   Rule Name	Name of a password change rule. The rule name must be unique in a bastion host.
   Timing	The options are Manual, Fixed-Time, and Cycle. Manual: Manually trigger the password change rule to change the password of the managed resource account. Fixed-Time: The password change rule is triggered by the bastion host to change the password of the managed resource account at a fixed time. This type of rule is executed only once. Cycle: The password change rule is periodically triggered by the bastion host to change the passwords of the managed resource accounts. This type of password change rule is triggered periodically.
   Execute Time	Date when the password change rule is executed. The default execution time is at 00:00 every day.
   Cycle Frequency	Password change interval. The unit is day. You need to set the End Time for this type of rules. Otherwise, the rule will be executed indefinitely.
   Method	How the password is changed. The options are Generate different passwords, Generate the same password, and Specify the same password. Generating a different password: The system randomly generates different passwords for managed resource accounts in compliance with password requirements. Generating the same password: Randomly generate the same password for managed resource accounts in compliance with password requirements. Specifying the same password: You manually change passwords of managed resource accounts to the same preset password you specify. NOTE: A password randomly generated by a bastion host contains 20 characters, including uppercase letters, lowercase letters, digits, and the following special characters %, -, _, and? A random password must contain at least an uppercase letter, a lowercase letter, and a special character.
   Options	The following options are supported: Allow to change the sudo account password: To change the password of sudo account, select this option, or the password of the sudo account cannot be changed. This option is not selected by default. Priority use of the sudo account to change password: To let the system automatically search for the corresponding sudo account and use it to change the account password, select this option. If no sudo account is available, the password can be changed using the current account. This option is selected by default. Allow to change the SSH Key: To let the system automatically change SSH public keys, select this option. NOTE: The Allow to change the SSH Key option is supported in version 3.3.36.0 and later only. To use this function, upgrade your bastion host to the latest version by referring to Upgrading the CBH System Version. If you select the key pair automatic login mode when managing host resources, enable Allow to change the SSH Key, or manual password change may fail.

5. Click Next and start to relate the ACL rule to one or more accounts or account groups.
   • After a password change rule is related to an account group, accounts automatically obtain the permissions of the rule the instant they are added to the account group.
   • If a password change rule is related to multiple managed resource accounts, batch changing passwords is available.

6. Click OK. You can then view the new password change rule in the rule list.

   To obtain the new password of the managed resource accounts, export host resource details by referring to Batch Exporting Host Resource Information.

7. Click Execute in the Operation column. In the dialog box displayed, confirm the execution. The policy updates passwords immediately.
