Here’s a detailed technical write-up on performing and understanding a factory reset on the ZKTeco UA300 access control & time attendance device.
The ZKTeco UA300 factory reset is a powerful recovery tool but results in complete data loss of users and logs. The menu method is safest when admin access exists. The hardware jumper method is the only way to bypass a lost admin password. Always verify the PCB revision and jumper location before shorting to avoid damage.
The ZKTeco UA300 is a biometric time and attendance terminal. Factory resetting the device is typically done to clear the database, reset communication settings, or remove an administrator who is no longer available.
Method 1: Reset via the Device Menu (If Admin access is available)
If you can still access the menu, this is the safest and most complete method. Press the M/OK key to enter the main menu. Navigate to System and press OK.
Select Auto Test or Advanced Settings (the name varies by firmware version). Find and select Factory Reset.
Confirm the action. The device will reboot with default settings. Method 2: Reset Admin Privileges (If locked out)
If you are locked out because of a forgotten administrator password or fingerprint, you can use a temporary "Backdoor" password based on the device's internal time.
Note the Time: Look at the current time displayed on the UA300 screen (e.g., 14:20).
Generate Password: Use the ZKTeco Admin Password Reset Tool or a similar utility. You enter the device time, and it generates a one-time password. Enter Backdoor: Press M/OK. When prompted for the Admin ID, enter 8888. Press OK and enter the generated temporary password.
Clear Admin: Once in the menu, go to User Management, find the administrator, and change their role to "Normal User" or delete them entirely. Method 3: Reset via Management Software
If the device is connected to a network, you can reset it using ZKTeco ZKTime.Net or similar management software.
Open the software and ensure the device status is Connected. Go to the Device Management or Terminal Management tab. Look for AC Manage or Device Maintenance. Select Clear Admin Privileges or Restore Factory Settings. Default Connection Settings
After a successful factory reset, the device will return to these defaults: IP Address: 192.168.1.201 Subnet Mask: 255.255.255.0 Gateway: 0.0.0.0 Admin Password: None (or 1234 for some older variants) To help you further, could you tell me: Are you locked out of the admin menu?

Overall Verdict: The factory reset process is effective but not user-friendly. It is the "nuclear option" for fixing firmware glitches, administrator password lockouts, or database corruption. However, the procedure is hidden, lacks official detailed documentation, and will completely erase all user data and settings.
Once reset, the initial setup is standard ZKTeco fare.
The factory reset function on the ZKTeco UA300 does exactly what it needs to do for troubleshooting access issues, making it a lifesaver for technicians who have been locked out by a forgotten admin password. However, for data privacy and security clearing, it requires an extra step through the software client.

Final Thoughts: If you are resetting this device because you forgot the password, it works perfectly. If you are resetting it to sell the device or repurpose it, ensure you verify that the fingerprint logs are manually deleted to ensure total privacy.
In the quiet corridors of the Meridian Office Complex, a small crisis was brewing. Sarah, the newly appointed HR manager, stood before the ZKTeco UA300
, a sleek fingerprint terminal that had suddenly become an impenetrable fortress. The previous admin had left without sharing the master password, and dozens of employees were now unable to log their hours.
"It’s just a machine," Sarah muttered, her eyes scanning the device's color screen. She knew that to regain control, she needed to perform a factory reset or at least bypass the admin lock. The Software Gambit
Sarah first tried the digital approach. She remembered a manual mentioning ZKTeco attendance software ZKTime 5.0
. If she could connect the UA300 to her laptop via a network cable, she might be able to clear the admin through the "Device Management" menu. She connected the device to her network and opened the ZKTime 5.0 Software She added the device using its default IP, often 192.168.1.201 Device Management , she looked for Advanced Functions to find the elusive "Clear Admin"
But the network was stubborn. The device refused to talk to her laptop. The "Super Password" Formula
Recalling a tip from an old IT forum, Sarah looked at the clock on the UA300's screen: Here’s a detailed technical write-up on performing and
. She grabbed a calculator, ready to try the "Super Password" trick often used for ZKTeco F18 and UA series : She took , subtracted the current time ( ), and got . Squaring that number ( ) gave her a long string of digits: : She pressed the button, entered
when prompted for an ID, and then typed her calculated "Super Password".
The screen flickered, and for a moment, Sarah thought she was in. But the clock ticked to 14:21, and the code expired instantly. The Final Reset
Desperate, Sarah turned to the hardware itself. Some models had a tamper switch
on the back. She carefully unmounted the UA300 from the wall.
"One last try," she whispered. She knew that if she could trigger the factory default settings, she would lose the user data, but at least the doors would open again. Following instructions for similar standalone terminals
, she looked for a reset sequence involving the tamper switch or specific DIP switches inside. Finally, with a long, satisfying
, the blue light flashed. The UA300 had surrendered. The admin lock was gone, and Sarah could finally start enrolling her team from scratch, ensuring she was the one holding the master key this time.
