Password for wifi or password for login tot he EX7000?
for the gui, if you didn't setup password recovery option, the only way to get that back is to factory reset the device. Then you'll be back to the defaults. Push and hold reset for 7-10 seconds while powered up. Or until the lights blink.
if you forgot wireless, you can hardwire into the device and go into its wireless settings to view/change the wifi password.
