I want to know if there is a possibility for changing the login and default password onto the device without modify defaults.rci, just directly on the configuration webpage. On your manual you tell there is the possibility on security page but I can’t see this page.
You can certainly change the login/password from the web interface. You cannot, however, affect changes to the ‘factory default’ settings, without accessing the customization interface and uploading a replacement defaults.rci file.
The user/password can be changed, on the web interface, from the Users menu.
