A: Use the physical reset button to restore factory settings – but again, the default becomes the sticker password, not a universal one.

Default passwords for ZKTeco devices are essentially public knowledge. Security researchers and documentation highlight several common combinations used across the platform: Root Access: Common pairs include root:solokey root:colorkey root:z1k2t3e4c5h Admin Access: Often defaults to admin:admin admin:1234 Web Interface: Default login is frequently administrator with the password Installation & User Guide - ZKTeco

Immediately change the root telnet password once access is gained. zmm220 default telnet password updated

Historically, many Linux-based embedded boards like the ZMM220 shipped with standardized, well-documented default root passwords for Telnet access. Why Telnet is Vulnerable

A: While some discussions may exist, accessing the device via Telnet without authorization is likely a violation of the manufacturer's terms of service and may be illegal depending on your jurisdiction.

Changing the default password is only the first step in protecting your biometric infrastructure. Implement these additional network security best practices to fully secure the ZMM220 platform. 1. Disable Telnet Entirely *1514885702# (fixed for device-to-device communication)

The new default Telnet password for the ZMM220 is:

Some users refer to changing the administrative web panel passwords on the device itself (e.g., from default values like 123456 or zkteco@12345 to something more secure). However, this is distinct from the underlying Linux Telnet credentials.

Some newer ZMM220 firmware platforms use more complex default strings found within their configuration files. A notable updated password found in ZKConfig.cfg for similar ZKTeco platforms is: z1k2t3e4c5h How to Recover or Reset a Lost Password Changing the default password is only the first

Stay secure, and happy configuring!

The update to the ZMM220’s default Telnet password marks a positive step toward a more secure industrial IoT ecosystem. No longer can an attacker simply try zmm220 versus root to compromise thousands of devices. However, the sticker password is still a , not a permanent solution.
