You can open the Change Password application from the Administrator tool or with the following URL:

http://<fully qualified host name>:<port>/passwordchange/

The Service Manager uses the user password associated with a worker node to authenticate the domain user. If you change a user password that is associated with one or more worker nodes, the Service Manager updates the password for each worker node. The Service Manager cannot update nodes that are not running. For nodes that are not running, the Service Manager updates the password when the nodes restart.

For a native user account, if you enable password complexity, use the following guidelines when you create or change a password:

The length of the password must be at least eight characters.
It must be a combination of an alphabet character, a numeric character and a non-alphanumeric character, such as:
! \ " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ ] ^ _ ` { | } ~

When you use special characters in a password, the shell sometimes interprets them differently. For example, $ is interpreted as a variable. In this case, use an escape character to escape the special character.
