Always follow best practices for security:
There is no official "crack" tool for Fatek PLC passwords, as the system uses hashed security rather than plaintext storage. To recover or bypass a password, you generally have three options: contacting the original developer, using official factory reset procedures, or employing specialized third-party services. đ ď¸ Official Recovery Methods
Contact the Machine Builder: Reach out to the original integrator who programmed the PLC; they often keep backups of the project files.
Fatek Support: Authorized distributors can help if you provide the serial number and proof of ownership, though they typically guide you toward a reset rather than retrieving the old code.
Full Memory Clear: You can erase the password by clearing the PLC memory, but this erases the entire user program. Power down the PLC.
Use a jumper on the pins labeled CLR (on models like the FBs series).
Power the unit back up; the ERROR LED will indicate the clear is successful. đť Third-Party Tools & Services
Several unofficial sources claim to provide software for password unlocking, though these carry security risks and varying success rates:
Specialized Software: Some sites like PLC Unlock BD claim to offer tools for the FBs series (up to version 5.83).
Technical Limitations: If a Fatek PLC screen displays "5%" during a password prompt, it is generally considered impossible to unlock via standard software means.
â ď¸ Security Warning: Exercise extreme caution when downloading "cracking" software from unofficial forums or YouTube links. These files frequently contain malware or can permanently corrupt the PLC hardware if the communication protocols are mismatched.
đĄ Key Takeaway: If you do not have a backup of the program, a "crack" may be your only hope of retrieving the logic, but it is often more reliable to reprogram the unit after a factory reset.
If you have lost the password for a Fatek PLC, "cracking" the software is generally not recommended as it risks corrupting the internal logic or hardware
. Instead, several official and community-supported methods exist to regain access or reset the device. Official Recovery Methods Manufacturer Support: For registered users, FATEK Automation Corp

The Vulnerability Landscape
Many older PLC models, including some in the Fatek FBs series, were designed in an era where physical security was the primary defense. As these systems became more interconnected, the following risks emerged:
Communication Interception: Legacy protocols often transmit data in plaintext. Tools that monitor serial or Ethernet traffic can sometimes capture password hashes or even plain strings during the authentication handshake.
Backdoor Passwords: Historical vulnerabilities in firmware sometimes included default or "master" passwords intended for factory recovery, which have since been documented in cybersecurity databases.
Brute Force Attacks: Without account lockout mechanisms, simple automated scripts can systematically test password combinations until the correct one is found. The "Crack" vs. Recovery Dilemma
While the term "crack" often implies malicious intent, in the industrial world, it is frequently associated with emergency recovery. Situations where a system integrator has gone out of business or an employee has left without documenting credentials can leave a facility in a "brick" state.
However, using unauthorized third-party software to bypass passwords carries significant risks:
Malware Infection: Many "PLC Unlocker" tools found on the internet are trojans designed to infect engineering workstations.
Logic Corruption: Forced access can sometimes corrupt the ladder logic or internal registers, leading to unpredictable machine behavior.
Legal and Compliance Risks: Bypassing security measures may violate service agreements or safety certifications (like SIL ratings). Best Practices for Modern Security
To move away from the need for password "cracks" and ensure your Fatek systems remain secure, consider these updates:
Firmware Updates: Always ensure your Fatek PLC is running the latest firmware. Manufacturers frequently release patches that close known authentication loopholes.
WinProladder Security Features: Use the built-in security settings in WinProladder to set complex passwords and define different access levels (e.g., read-only vs. edit rights).

The air in Sublevel 3 of the Ichihara Chemical Plant smelled of rust and regret. Kenji Saito, a controls engineer with tired eyes and a caffeine dependency, stared at the flickering screen of his laptop. The FATEC PLC controlling the plantâs critical sodium hypochlorite reactor had just thrown a fatal watchdog error. Worse, the previous engineerâa man who believed job security meant burying passwords in forgotten foldersâhad left no documentation.
âTry âAdmin123,ââ said Yuki, his junior colleague, peering over his shoulder.
âI already tried that, the birthdate of his dog, and the name of his favorite baseball team.â Kenjiâs fingers hovered over the keyboard. The reactorâs pressure gauge was climbing. In twenty minutes, either he found a way in, or theyâd have to perform an emergency ventâa move that would cost the company half a million yen in lost product and another million in environmental fines.
He needed a different angle.
The FATEC PLC used a legacy access protocolâpassword hashes stored in a non-volatile memory block. Normally, youâd need the proprietary software and a direct programming cable. Kenji had both. But the password field was a black box. Three failed attempts and the PLC would enter a lockout state, forcing a full reset and loss of the control logic.
This was attempt number two.
âYuki, go find me the old commissioning reports. Anything from 2017.â She nodded and sprinted toward the maintenance shed.
Kenji opened a different toolâa custom Python script heâd written six months ago during a slow night shift. It wasnât a cracker in the brute-force sense. It was a timing attack tool. Heâd noticed that the FATECâs legacy protocol responded slightly faster when the first byte of the password hash matched. A microsecond difference, but measurable. Heâd refined it on a test unit in his garage, never thinking heâd use it in a live plant.
He connected the RS-232 cable, launched the script, and fed it a list of common hash prefixes. The PLCâs reply times were jitteryâindustrial interference from nearby motorsâso he let the script run ten thousand probes per candidate, averaging the results. His laptop fan whined.
After ninety seconds, a pattern emerged. Byte one: 0x7A. Byte two: 0x3F. Slowly, like assembling a jigsaw in the dark, the hash revealed itself.
7A 3F 8C 20 11 99 42 04
It wasnât a password. It was a hash. But Kenji didnât need the plaintextâthe PLC compared hashes directly. He modified his script to replay the complete hash in the authentication handshake.
The screen blinked.
ACCESS GRANTED. SYSTEM MODE.
Kenji exhaled. He navigated to the watchdog timer, reset it, and manually lowered the reactorâs agitator speed. The pressure gauge began to fall.
Yuki returned, out of breath, holding a dusty binder. âFound it! The password was âFATEC#2017ââwait, youâre already in?â
âYeah.â Kenji unplugged the cable. âBut donât delete that binder. Burn it into your memory. The next time this happens, I might not be here.â
He saved a copy of the hash extraction routine to a hidden directory, labeled plc_recovery_tool.py. Then he walked to the window, where the first light of dawn was cutting through the refinery haze.
The plant lived another day. And somewhere in the dark logic of a forgotten Japanese PLC, a backdoor no vendor had ever documented remained openâjust in case.
