What is the default password?

The default password is either ubnt/ubnt or ui/ui - depending on when the device was manufactured and its firmware version.

UniFi devices use ui/ui and the UXG, USG and UniFi OS Consoles use root/ui. So if you are setting up a new device, try these new passwords, along with the old ones, if you are having issues.
