Always enroll at least two separate fingers per employee during onboarding. Register a backup proximity card or secure PIN code for every user.
On certain ZKTeco devices like the ZK-AL10DB and ZK-AL20DB smart locks, a physical or software lockout switch determines which users can gain access.

If the administrator password has been forgotten, physical access to the device may be required for password recovery. Options include:
Perform a hard reboot by disconnecting the power for 30 seconds. This often clears temporary software glitches. License Clearing (USB Method): Hardware & Biometric Sensor Maintenance For systems linked
