Legacy Pro-Face panels (GP2000 series and older) store passwords using weak encryption algorithms. Industrial recovery tools can read these passwords from a backup file.

Before attempting an unlock, it is essential to understand how Pro-face structures its security. Pro-face HMIs (such as the GP3000, GP4000, or SP5000 series) use different password layers depending on the software used to program them (GP-Pro EX or Pro-PB III).

Searching for a is often a moment of panic. You are not alone. Thousands of technicians face this locked screen every year. This article provides a definitive, step-by-step guide to legitimate unlocking methods, the built-in backdoors Proface provides, software tools, advanced hardware solutions, and the critical legal ethics you must understand.

Prevention is always better than a cure. Implementing these practices will save you from future password crises.

Insert a FAT32-formatted USB flash drive or SD card into the HMI.

A factory reset completely erases the runtime application from the HMI. The machine will not function until a valid project is reloaded. How to Perform a Factory Reset Power off the HMI unit.

Do you have the , or are you trying to retrieve the data directly from the unit ? If you forget your password

If you have a backup project file ( .prx ) but cannot open it in GP-Pro EX because it asks for a project password, the password hash is stored within the file binary.

This will delete the current project and data from the HMI, requiring a fresh download from GP-Pro EX. 4. Forcing a Project Download

: When prompted for a password to proceed with initialization, enter 1101 .

If the HMI is relatively new or has recently undergone a factory reset, it might still be using the default manufacturer credentials.

Navigate to → [Initialize User Memory] or [Initialize GP Memory] .

If the backup was saved without password encryption, you can open it directly in GP-Pro EX. Third-Party Software and Script Decryption

: Every password unlock or reset attempt is logged within the HMI’s internal system alarm history, providing a clear record for security audits.
