Used for the Pro-face Remote HMI application on smart devices, this password secures remote access to the HMI. The default connection password is often !Proface1234 .

This will delete the existing project and all data on the HMI.

Understanding what needs "unlocking" is the first step, as Pro-face HMIs utilize three distinct, independent password types: System Password (Offline Mode): Used for the Pro-face Remote HMI application on
This erases the existing runtime project. Ensure you have a backup, or you will lose machine logic (though the PLC remains unaffected).
The password should now be reset to default or cleared, allowing you to access system settings. Method 2: Resetting via Project Update
Modern Pro-face panels programmed with GP-Pro EX use a multi-level security matrix: : Select "Initialize User Memory" and "Initialize Backup
If you have lost the offline/system password, you cannot directly bypass it without altering the unit. Method 1: Initializing GP Memory (Factory Reset)
This is the master key for the HMI's internal configuration. When you attempt to enter the "Offline Mode"—the system's maintenance and settings menu—you are often prompted for this password. The default factory password for many Proface HMI models is commonly 1101 . However, this is frequently changed by integrators, leading to lockouts.
Press and hold the (or specific diagonal corners depending on the model) of the touch panel. Power on the unit while maintaining pressure on the screen.
: Passwords are saved in an encrypted format within the HMI's internal memory to prevent unauthorized extraction via physical hardware tampering.
To prevent password-related issues and ensure the security of your Proface HMI, follow these best practices:
