Hello @aquablue, @Kenny & @amaranth,
Peplink already has an excellent way to almost instantly secure all Peplink appliances including FusionHub when you use InControl2, add the serial number to a group within InControl2 and make sure you enable the “Device Web Admin Management”.
(PS this is an example admin username & password if manually set, the “Assign a random password for each device” is excellent also)
If the organisation you are setting up any appliance/FusionHub is not going to operate with InControl2, you can still do this option to create immediate installation security. Once secured you can then remove the device from the InControl2 group & go into the Web Admin of the appliance/FusionHub to turn off InControl2 functionality.
Happy to Help,
Marcus
