6.4 User management
In the "User management" menu, you can switch user management on or off. If user
management is switched on, all users must log on in the login area of the WBM to be able to
make changes in the WBM. If the user management is disabled, the settings of the "WEB"
user profile are automatically applied.
Depending on your own user role and whether your user profile has been granted
administrator rights, you can manage "User profiles" in this menu.
User management
NOTICE
Save the device configuration before activating user management
Export your device configuration before you activate user management. If you experience
compatibility problems with your Web browser and https encryption which require you to
restore the factory settings of the reader, this situation provides you the option of reverting
to the previous state.
Click the "Switch on user management" button to activate user management. After user
management has been activated, each user must log on to the WBM in the login area.
