I'm assuming you're referring to Xinjie PLC, a type of programmable logic controller used in industrial automation. I'll provide a general overview of the topic, while emphasizing the importance of cybersecurity and responsible disclosure.
Background
Xinjie PLC is a Chinese company that produces a range of programmable logic controllers (PLCs) used in various industries, including manufacturing, energy, and infrastructure. PLCs are computer-based control systems that monitor, control, and automate industrial processes.
Password Cracking and PLC Security
In 2021, concerns emerged about the security of Xinjie PLC devices, specifically related to password cracking. Password cracking refers to the process of guessing or recovering a password to gain unauthorized access to a system. In the context of PLCs, a cracked password could allow an attacker to manipulate the device, access sensitive data, or disrupt industrial processes.
Research and Disclosure
Researchers and cybersecurity experts have investigated Xinjie PLC devices for potential vulnerabilities, including weak passwords or password storage practices. In some cases, these investigations have led to the discovery of vulnerabilities, which can be used to gain unauthorized access to the device.
In 2021, a security researcher reportedly discovered a vulnerability in Xinjie PLC devices that allowed for password cracking. The researcher claimed to have found a weakness in the device's password storage mechanism, which made it possible to recover the password.
Mitigation and Recommendations
To mitigate the risks associated with Xinjie PLC password cracking, users and administrators should:
Responsible Disclosure
It's essential to emphasize the importance of responsible disclosure in cybersecurity research. When researchers discover vulnerabilities, they should report them to the manufacturer or affected parties in a responsible and confidential manner. This allows the manufacturer to develop and distribute patches or mitigations before the vulnerability is publicly disclosed.
Conclusion
The Xinjie PLC password crack vulnerability highlights the importance of cybersecurity in industrial automation. By taking proactive measures to secure PLC devices, users and administrators can minimize the risks associated with password cracking and other potential vulnerabilities.

Research from 2021 and 2022 identified critical vulnerabilities in Xinje PLC software that could allow unauthorized access or "cracking" by bypassing security measures. Security Vulnerabilities (2021-2022)
In 2021, security researchers discovered two major vulnerabilities in the Xinje PLC Program Tool v3.5.1 xinje plc password crack 2021
, which could be leveraged to gain unauthorized code execution or manipulate PLC files: CVE-2021-34605
: A vulnerability that could allow an attacker to write arbitrary project files to a PLC. CVE-2021-34606
: Another flaw in the same version that could trigger code execution via a specially crafted project file. Known Models Subject to Password Cracking
Third-party services often specialize in "unlocking" or "cracking" passwords for older Xinje models, typically those in the XC3 Series
: Includes models like XC3-14, XC3-24, XC3-32, XC3-48, and XC3-60 (R/T/RT variants). XC5 Series : Includes XC5-24, XC5-32, XC5-48, and XC5-60 models. Methods & Risks Software Bypassing
: Some tools claim to read the password directly from the PLC's memory without deleting the existing program. Safety Warning
: Attempting to crack PLC passwords can lead to permanent data loss or "bricking" the hardware if not done correctly. Industrial security experts recommend upgrading to the latest firmware to patch the vulnerabilities identified in Claroty's 2021 research

I understand you're looking for information on recovering or resetting passwords for XINJE PLCs (Programmable Logic Controllers), particularly from around 2021. However, I must clarify that providing or promoting methods to "crack" passwords on industrial control systems raises significant legal, ethical, and safety concerns.
Instead, I will provide a detailed, responsible article covering legitimate recovery methods, default credentials, official vendor procedures, and important security practices for XINJE PLCs — especially relevant for engineers, maintenance technicians, and system integrators who may need access to a locked PLC.

Searching for “xinje plc password crack 2021” yields many forum posts, YouTube videos, and shady websites offering “tools” or “services.” Most are:
From a cybersecurity perspective, if a 2021+ XINJE PLC password were trivially cracked, it would violate basic industrial safety standards (IEC 62443). XINJE has improved password hashing in recent firmware, making offline cracking infeasible without vendor cooperation.
Before attempting any advanced recovery, always test default credentials. From 2021 firmware onward, XINJE has maintained certain factory defaults:
| Model Series | Default Upload/Download Password | Default Monitor Password | |--------------|----------------------------------|---------------------------| | XC Series (XC1/XC2/XC3) | 00000000 or 88888888 | 00000000 | | XD Series (XD1/XD2/XD3/XD5) | 00000000 | 00000000 | | XL Series | 00000000 | None (disabled) | | XJ Series | 00000000 | 00000000 | Change default passwords : Ensure that all default
Note: In 2021+ firmware updates, XINJE began requiring users to set a password during first project download if security was enabled. If the original engineer never set a password, leaving all password fields blank or "00000000" in the software interface will allow access.
Try this first: In AutoShop software, go to PLC → Online → Enter Password, try leaving it empty or entering 8 zeros.
