Best practice recommends changing from the well-known default to a unique password, especially for internet-connected HMIs.

: Configurable timers that reset access after periods of inactivity.
Typically, developers define levels (e.g., Level 0: Operator, Level 1: Maintenance, Level 2: Engineer). Higher-level tasks require higher-level passwords.
The standard engineering solution is to locate the original source code backup on the development PC, modify the password settings in the Workbench, and overwrite the HMI via a wired connection. This will wipe the old password data. Typically, developers define levels (e
:
| Function | Script Function | Purpose | |----------|----------------|---------| | Login | !LogOn() | Opens login dialog box | | Logout | !LogOff() | Terminates current user session | | User Management | !Editusers() | Opens user management interface | | Change Password | !ChangePassword() | Allows password modification |
Define the overarching roles (e.g., Administrators, Engineers, Operators). This will wipe the old password data
The true "work" begins when a developer sets up custom security. In the MCGS configuration software, users are typically assigned to (1-15).
If the issue is with the HMI unit itself and no operator password is set, you can often force a hardware reset.
