ZKTeco devices typically operate over a TCP/IP network and are managed via a Web UI, SDK, or client software. The vulnerability lies in the authentication layer of these services.

ZKTeco default passwords typically vary by product type, such as biometric terminals, IP cameras, or management software. For most standard biometric devices without a set administrator, the default web interface credentials are for the username and 123456 for the password. Common ZKTeco Default Passwords by Category ZKTeco devices typically operate over a TCP/IP network
The security industry operates on a paradox: the strongest locks are often controlled by the weakest keys. ZKTeco, a global leader in time attendance and access control solutions, deploys millions of devices worldwide. While the biometric sensors (fingerprint, facial recognition) provide a high assurance of identity for the user , the administrator interface is frequently protected by factory-default credentials. Default credentials should never be used to access
Report compiled from ZKTeco official manuals, CVE records (e.g., CVE-2020-28346 related to ZK credentials), and penetration testing guidelines.
The default password is often 123456 for the administrator account.
Utilizing scanning tools (such as Shodan), researchers can identify thousands of ZKTeco web interfaces exposed to the public internet. A significant percentage of these accept default credentials, granting unauthorized access to:
