Ensure HMIs are isolated on a dedicated Manufacturing Zone VLAN, protected by an industrial firewall. Restrict Ethernet-based project uploads to authorized engineering workstations only.
But what happens when legitimate access is lost? An administrator leaves the company. A former integrator doesn’t hand over credentials. A forgotten password locks a critical production line. This guide covers all to regain access to an Omron HMI without resorting to “cracking.”
If the unit is old and the password is lost, it may be time to upgrade to a newer, more secure HMI model.

A high percentage of industrial software cracks shared on public file-sharing networks contain trojans designed to infiltrate corporate engineering workstations.
: Some Omron HMI models allow for a reset to factory defaults, which usually comes with default login credentials. This method, however, might erase all the configurations and data stored on the device. Ensure HMIs are isolated on a dedicated Manufacturing
The NA series represents Omron's modern, highly secure HMI lineup. Programmed via Sysmac Studio, these devices leverage modern cryptographic standards. Project files are heavily encrypted, and user authentication can be tied to secure network protocols. True password "cracking" on modern NA series hardware is virtually impossible using legacy hex-editing methods, requiring a complete project overwrite if credentials are lost. Cybersecurity Risks of Using Public Crack Tools
Forum discussions about NS10-TB00B-V2 units highlight the common scenario of inheriting equipment with unknown project passwords when original programmers are unavailable. An administrator leaves the company
The process of recovering an Omron HMI password typically involves several steps, and the exact method can vary depending on the model of the HMI and its firmware version. Here are some general approaches:
Before attempting to crack a password, it is recommended to try common Omron default passwords. Many legacy systems might not have had their passwords changed by the original installer.
The NA series (running Sysmac Studio) implements more sophisticated security features. Password policies can enforce regular changes, and user management functions like ModifyUser exist (though largely undocumented). As one forum member noted: "Changing password is different although it appears you can use the ModifyUser function above to do this. These functions are undocumented so Omron apparently does not have examples".
