Hello i have a mikrotik like SXTsq i want to lock the device from using or from logging in winbox or prevent it to make a software in netinstall i want only me can access the device
See https://help.mikrotik.com/docs/display/ROS/RouterBOARD#RouterBOARD-Protectedbootloader. You can disable the Winbox service but that will prevent anyone using it, a usual recommendation is to make Winbox accessible only via a VPN connection to or from the device.
So for example i have SXTsq and the reset button is disabled how to enable the reset button and reset the device
Set reformat-hold-button and reformat-hold-button-max. The device cannot be reset, only completely reformatted by holding the reset button for a time between the two values and will then require a netinstall as described in the link provided.
bro i tried if the reset button disabled so how i hold on reset button while using netinstall because there is no getting mac in winbox and in netinstall
