With the <Password function> activated the <Login> option can be used in order to
change the current user.
Please see chapter 7.3.5 Password settings and user permissions for details about
the <Password function>.
For the currently logged in user it is also possible to log out in order to prevent parameter
changes by unauthorized staff.
The current state of the <Password function> is indicated in the upper right corner of
the main window. When there is nothing indicated the password function is disabled.
