Rockwell Automation (Allen-Bradley) users who have lost passwords should contact Rockwell support directly rather than resorting to third-party cracking tools. In 2025, CISA issued 32 ICS advisories highlighting security issues in Siemens and Rockwell OT equipment, including insecure access to HMIs and weaknesses in third-party components. Attempting to use cracking tools on Rockwell devices could violate security policies and trigger further alarms.
Some tools rapidly guess combinations via the communication port.
These tools are frequently Trojan horses designed to inject malware into industrial control systems (ICS). Using cracking software can be considered a criminal
| Manufacturer / Device | Official Password Recovery Method | Effect & Key Consideration | | :--- | :--- | :--- | | | Program Storage Card: Insert a blank or specially prepared SIMATIC memory card into the PLC. Upon power-up, the card can force the CPU to reset to factory defaults, wiping all passwords and user programs. | Clears everything. Requires legitimate ownership. Some community methods also use an SD card with a specific process involving power cycling. | | Siemens S7-200 | Clear PLC Memory: In the STEP 7-Micro/WIN software, go to PLC > Clear . Select all block types and confirm by entering the password CLEARPLC . | The universal string CLEARPLC serves as a master key to erase memory and reset the CPU. | | Rockwell Automation | Clear Memory Command: For MicroLogix controllers, the software can be forced to clear the program using a special numeric command 65257636 (the keypad equivalent of "MLCLRMEM"). | A specific backdoor command erases the program. For PanelView HMIs, there is no password recovery; a "restore terminal operation" is required. | | Mitsubishi | Third-party Software: There is no official "password recovery" tool. However, multiple unofficial software utilities claim to read or reset passwords for FX, A, and Q series PLCs by connecting via the programming port. | These are not manufacturer-supported. | | General (Many HMIs) | Factory Reset: This involves accessing the HMI's BIOS or boot menu (often via keypresses on startup) and selecting a "Factory Reset" or "Reset to Defaults" option. | Destructive. Returns the device to a clean slate. |
