This guide explores the legitimate methods for Pro-face HMI password unlocking and how to recover your project files safely. Understanding Pro-face Password Levels
Unlocking a Pro-face HMI is straightforward if you have the source software, but it becomes a challenge if you are trying to "reverse" a project off a live unit. Always try the default passwords and check your offline system settings before resorting to a full memory wipe.
The most common issue occurs when an engineer needs to pull a project from an old HMI (Upload) but does not know the transfer password. Checking Backup Memory (CF Card / SD Card / USB) proface hmi password unlock
When official methods fail, technicians turn to third-party recovery software. Use these only on equipment you legally own.
Unauthorized software attempts to force data into the HMI's EEPROM. A minor communication glitch during this process can permanently brick the HMI hardware.
This erases the existing runtime project. Ensure you have a backup, or you will lose machine logic (though the PLC remains unaffected). Note: This method deletes the old password configuration
Some technicians build a Raspberry Pi script that continuously sends password attempts to the HMI’s FTP or Web server (port 21 or 80). This is (one attempt per second). A 4-digit code takes 2.7 hours maximum. An 8-digit code takes 3 years.

Select > Pro-face Remote HMI Settings .
Disable the "Transfer Password" feature during commission phases, and only apply it when handing the machine over to production if corporate policy strictly dictates it.
If you have the original project file on a backup computer, you do not need to crack the password. You can overwrite the existing security settings. Steps to Reset via GP-Pro EX: Open the original project file ( .prx ) in . Navigate to Common Settings in the project tree. Click on Security Settings and select Password Screen . Change or disable the password.
