Change the password for authorized users or the password
encryption key
When to do
For security reasons it is advised to periodically change the password of the three access modes
(Key operator, System administrator, Power user).
For local accounts you can do this in WebTools Express.
When network authentication is enabled, this is handled by the IT password policy.
[Password encryption key]
This key is used to securely encrypt all stored password on the device. Not knowing this key, it is
impossible for a third party to decrypt any stored password. It is advised to change the system
default password encryption key after the system is installed, re-installed or upgraded.
You can find this setting in the same section as the passwords.
IMPORTANT
Handle and store all passwords securely and with care. In case of forgotten passwords, a service
technician can reset the Key operator, System administrator, Power user passwords only when
his rights have been enabled by the System Administrator. ([Security] - [Configuration] -
[Permissions for Service] - [Allow Service technician to reset passwords] - [Yes]). Otherwise the
machine has to be reinstalled.
Procedure
1. Open the [Configuration] - [Connectivity] tab.
2. Under the [Passwords] section, select [Local Key Operator password], [Local System
Administrator password], [Local Power User password], or [Password encryption key] depending
on the setting you want to change. A new window opens.
