As system administrator, there are two different ways to edit the system administrator's user master data:

• Option 1: Select the menu item "User Data" → "User master Data" via the menu. 
• Option 2: Via the tile "User Master Data".

The data of the user "sysadmin" is displayed directly. There are 2 tabs, User and Communication.  However, the data in the Communication tab and the data in the Master Data area cannot be changed.

You can find a detailed description of the settings under:

• User Master Data

Finally, the password can be set again via the Set new password button.

The entry of the new password must be repeated and saved for the change to become active.
