15.1 Requirements for a Secure System Password
From the perspective of system communication, all devices with the same password form a system.
For this reason, a password used for all devices in a system is called a system password. You can
only access all devices in your system with the Cluster Controller if all devices have the same system
password.
The system password that you enter for your respective user group when logging into the
Cluster Controller user interface for the first time is a default system password. For security reasons,
you should change the default system password as soon as possible following commissioning (see
Section 15.2, page 83).
You can increase the security of your system password with the following measures:
• Select system passwords containing at least eight characters.
• Use combinations of upper-case and lower-case letters, special characters and numbers.
• Do not use names or common words (e.g. "dog", "cat", "house").
• For the system password, avoid using words that have any personal relevance to you such as
the names of persons or pets, personnel numbers, identification numbers or car license plates.
• Do not repeat names or words (e.g. "househouse" or "catcat").
• Do not use combinations of numbers or letters in the same order as they appear on your
keyboard (e.g. "12345", "qwert").
