If you are locked out of a project file within GP-Pro EX, look for a "Forgot your password?" link on the login screen, which may provide an email-based reset method. If you are dealing with a start-up password and the HMI application allows it, the Skip Password Screen function might be enabled in the settings, allowing you to bypass this screen entirely.
A: Partially. You can attempt the default 1101 via the touch screen. For full removal, you need a PC and GP-Pro EX.
Bypassing an upload password to copy a machine builder's proprietary code may breach End-User License Agreements (EULAs) or legal contracts. Best Practices for HMI Password Management proface hmi password unlock

In the world of industrial automation, Proface stands as a titan. Their Human-Machine Interfaces (HMIs)—from the classic GP series to the modern SP5000—are the dashboard of the factory floor. But there is a moment of dread that every maintenance technician or production manager knows too well: You boot up the HMI, and instead of the production screen, you are greeted by a password prompt. If you are locked out of a project
Before resorting to more complex methods, it is always wise to try the most common default passwords. Many older or second-hand units may still use factory-default codes. These often include:
If you have lost the offline/system password, you cannot directly bypass it without altering the unit. Method 1: Initializing GP Memory (Factory Reset) You can attempt the default 1101 via the touch screen
Unauthorized software attempts to force data into the HMI's EEPROM. A minor communication glitch during this process can permanently brick the HMI hardware.
Before attempting technical overrides, test common factory defaults or industry-standard placeholders often left by integration engineers: control password 1234 or 123456 0000 The HMI model number (e.g., GP4000 or 3000 ) 2. The Backup Memory Card/USB Method
Being locked out of a Proface HMI is a stressful but solvable problem. Your approach will depend on the type of password in place and your level of access. Always begin with the simplest solutions: try default passwords and attempt to read the project file via GP-Pro EX. If those fail, a full initialization of the HMI from Offline Mode is often the most straightforward solution, though it requires a project backup. For the most secure blockages, professional decryption services are the final, surefire solution.
If you want, tell me the exact Pro-face HMI model and whether you have the project file or backups; I’ll provide model-specific recovery steps (including where to find the factory-reset procedure).
