The most efficient way to regain access is through the ZKTeco attendance management software. If your device is connected to your local network (LAN), you can use the software as a remote reset tool. Steps to Reset via ZKTime/ZKBioAccess: The most efficient way to regain access is
If a malicious actor has physical access to a ZKTeco terminal installed on a wall, they can often reboot the device into "Test Mode" or access the communication ports. If the device is protected only by a lost password, a reset tool allows the attacker to gain admin rights, delete logs, and open doors controlled by the device.

The ability to generate super passwords based on serial numbers creates a vulnerability that relies heavily on the obscurity of the algorithm.
