Arduino PRIMO, STAR OTTO, UNO WiFi OTA programming password protection

Greetings, I know Arduino PRIMO and START OTTO aren't out yet but, for what I get from the guides, after I connect the board to my WiFi network and setting the board in STA mode, I can freely see the board on the network and I can upload a sketch without any password, unlike what happens with Arduino Yun, Tian and Industrial 101 (that ask for linino root password when programming via OTA).

Am I wrong? Isn't this a potential security issue as soon as someone manages to connect to my WiFi network?
