Ensure that system integrators provide unmapped, password-free source code backups upon project completion and sign-off.
Check the project documentation or the control cabinet's physical logbook for written passwords.

: Excellent multi-level security (up to 15 levels). You can assign specific passwords to certain screens or buttons, preventing unauthorized operators from changing critical machine parameters.
Keep a secure, encrypted log of HMI passwords. : Excellent multi-level security (up to 15 levels)
When the project on the HMI is the only copy and it is password-protected against uploading, things get tricky. Pro-face uses encryption to protect intellectual property.
These passwords operate on the physical screen during production. They restrict access to specific operational screens, calibration menus, or system settings. They are managed via security matrices within the active project. 2. Official and Safe Recovery Methods
If the project file itself is password-protected from being opened, you will need the original developer's credentials. Method 3: Forced Format (The "Fresh Start" Approach)
Before attempting an unlock, it is important to identify which "door" is locked. Pro-face typically uses two types of protection:
