For safety, it is best practice to log the user out automatically after a period of inactivity.

There are specialized services that offer password recovery for HMI project files (decompiling .exob or similar files). These are often used when the original programmer is no longer available. 4. Security Best Practices for the Future
For HMIs, passwords typically secure different levels of access, such as system settings, project uploads, or FTP servers. If you are locked out, you can try standard factory credentials or use specific software-based recovery methods. Common Default Credentials
: This often involves a specific "tap sequence" or holding the screen during startup. : Resetting to factory defaults will typically erase the current project data Software Configuration : Within the MCGS configuration software MCGS Pro Designer ), passwords can be set or changed by navigating to the "Security" "User Management" settings in the project tree. Troubleshooting Access Issues Invalid Attempts mcgs hmi password work
Setting up and managing passwords involves specific steps within the MCGS design software. Setting Up User Accounts Open your project in the MCGS Workbench.
666666 or 888888 are sometimes used for restricted system-level menus. 2. Identifying the Protection Level
This security layer prevents unauthorized retrieval of the project compilation files from the physical HMI hardware back to a PC.
Understanding how MCGS HMI passwords work is about more than just learning which button to press or which script to write. It is about adopting a mindset that values security as a core operational principle. The built-in tools from Kunlun Tongtai provide a highly functional, robust foundation upon which you can build any level of security you require, from a simple password prompt to a complex, time-based, multi-user system with granular control over every aspect of the interface. For safety, it is best practice to log
If you simply need the hardware to work and don't care about the existing program, you can perform a factory reset via the SD card or USB recovery mode. This will wipe all data, including the password and the project. 4. Changing the Password during Runtime
: Link login status to system variables like !UserManage for dynamic control. 3. Core Functional Components 🚀 Key Security Features
: Restrict access to specific buttons or screens, ensuring only authorized personnel can start or stop processes.
MCGS, primarily developed by Beijing Kunlun Tongtai, is a ubiquitous presence in the world of industrial automation, powering countless machines in sectors from heavy manufacturing to sophisticated packaging lines. The platform is prized for its flexibility, power, and affordability. But with great power comes great responsibility—the responsibility to ensure that only the right people have access to the right functions, and this is orchestrated through a multi-layered password and user privilege architecture.

Our focus here is on the that empowers operators and engineers to securely run the machine.
Before writing a single line of script, you must configure the user database. This is done in the MCGS development environment. As shown in multiple tutorials, the process is straightforward:
Connect via Ethernet (default IP is often 192.168.1.200 ) or RS-232.
If this screen wasn't built into the project, you cannot change the password while the machine is running; you must modify the project in the MCGS software and redownload it. 5. Best Practices for Engineers To avoid "password lock" issues in the future: of the original .mcg project file.
