There is another small sticker with default password at the back of the device where the wiring interface board inserted to, that sticker will always be there if user not removing it on purpose.
We suggest user to change the default password and store the administrator password in safe places. We do have customer changed the password but forgot and lost for somehow human error. Then follow User Manual and using the shipped Wiegand cable can factory reset the device. This requires user to open the device and we do this on purpose for security reason because we do not want anyone can easily press some button to reset this device.
Yes, if open ticket and contact GS Support will get the default password. But that takes time and for everyone’s benifit, we do NOT encourage users to do this unless no choice. Yes, the password is unique and linked to MAC address and other unique product information.
