For security reasons it is advised to periodically change the password of the three access modes (Key operator, System administrator, Power user) in WebTools Express.
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.
