You may encounter third-party tools claiming to "crack" or "read" Delta HMI project passwords from .DPS, .DPA, or .DOP files.
How do I set a password for projects on HMI? - Delta Electronics
Unlocking a password-protected Delta HMI (such as the DOP-B or DOP-100 series) typically involves either using the default credentials or, in cases of forgotten passwords, using specialized "reader" or "crack" software. Common Default Passwords
Before attempting to use third-party unlocking tools, try the factory default passwords often used in Delta's environment: Secondary: Welcome to Delta Methods for Unlocking & Password Recovery
If the default password fails, there are several methods used by technicians to regain access to project files: Project Password Readers Certain tools can read the password directly from the project files. How it works:
Some software tools allow you to copy a specific numeric string from the project file's metadata and convert it into the actual alphanumeric password used for project protection. Specialized Unlock Software
Third-party developers offer "PLC/HMI Unlocker" tools that target the series. These tools are often marketed as all-in-one solutions
for cracking passwords and disabling "Anti-Upload" protections. Note: Many of these tools are distributed via forums or Facebook service groups and may require payment or a specific license key. Communication/Upload Password
If you are trying to upload a program from the HMI to a PC and it asks for a password, this is usually the "Upload Password" set within under the Configuration menu. Tools like the Delta PLC Password Tool
are sometimes used to manage or bypass these security levels. Manufacturer Official Path
If the HMI belongs to a machine you purchased, the most reliable and legal method is to contact the Original Equipment Manufacturer (OEM)
. They can provide the project password or the original source code. Delta Electronics generally does not provide password-bypassing software to the public to protect intellectual property. Important Note: Using "crack" software may violate the Terms of Service for Delta software
When a Delta Human Machine Interface (HMI) is password-protected and the credentials are lost, users typically seek ways to recover the project file or reset the device. While "unlocking software" is often searched for, it is important to distinguish between official recovery methods and third-party tools that may pose security risks. 1. Official Recovery & Reset Methods
The primary way to manage or remove passwords for Delta HMIs is through the official DOPSoft software provided by Delta Electronics.
Project Upload: If you have physical access and the project is not "Upload Protected," you can use DOPSoft to upload the program to a PC. If a password is required and unknown, you cannot access the logic without it.
System Menu Reset: For some models, you can enter the system menu by pressing the SYSTEM button on the rear of the HMI for 3 seconds during power-up. From here, you can often perform a factory reset, which deletes the project and all passwords, allowing a fresh download.
Default Passwords: Delta HMI software often uses 12345678 as the default highest security password unless changed by the programmer. 2. Third-Party "Unlock" Software
Various third-party websites offer tools claiming to "crack" or "read" project passwords for Delta DOP series HMIs.
Mechanism: These tools typically attempt to read the password directly from the uploaded .dps, .dpa, or .dpb project files by exploiting how the software stores security strings.
Security Warning: Security researchers have warned that many HMI/PLC password-cracking tools found online are bundled with malware or exploit zero-day vulnerabilities to infect the user's computer. Using these tools in an industrial environment can compromise the entire network. 3. Password Management in DOPSoft
To avoid lockouts, it is recommended to manage security levels correctly within the DOPSoft environment: Navigate to Options → Configuration. Select Security Level and Password.
Set distinct passwords for different user levels to prevent unauthorized changes while ensuring an administrator maintains "Highest security" access. Summary Table: Access Restoration Forgotten Project Password Delta Hmi Password Unlock Software
Check for default 12345678. If that fails, the original source code or an "unlock" service may be required. Forgotten Upload Password
Access to the device is restricted. A factory reset via the physical System button is usually required to clear the device. Lost Admin Access
Use Delta Service Support or an authorized distributor to see if a hardware-level recovery is possible for your specific model.
Important Note: Unauthorized unlocking of industrial hardware may violate end-user license agreements (EULA) and should only be performed on equipment you own or have explicit permission to modify. AI responses may include mistakes. Learn more
How do I set a password for projects on HMI? - Delta Electronics

If you’ve ever been locked out of a critical industrial system because of a forgotten password or a predecessor who left without a "handover," you know the sheer panic of seeing that password prompt on a Delta HMI. Third-party "Delta HMI Password Unlock" software often feels like a magic bullet for these high-stress situations, but it comes with a major "proceed with caution" sign.
Here is a review of what this software actually brings to the table—and the risks you should know about. The "Hero" Moment: Functionality
For engineers in a bind, these tools are designed to do one thing: bypass or recover passwords for Delta's DOP series or other HMI projects. The Appeal:
They can often read the "clear text" password directly from the HMI’s EEPROM or project file, allowing you to regain access without wiping the program. Ease of Use:
Many of these tools are remarkably simple. You connect your PC via a serial or Ethernet cable, run the utility, and it attempts to find the vulnerability that leaks the security key. The "Shadow" Side: Security & Safety
While these tools can save the day, they are rarely "official" and carry significant baggage. Malware Risks: Research from cybersecurity firms like
has shown that many free HMI cracking tools found on the web are actually "Trojan horses". They might unlock your screen, but they also install malware like
on your workstation, which can steal data or disrupt your network. Stability Issues: Since these aren't Delta Electronics
products, they can occasionally brick the HMI or corrupt the project file during the "cracking" process. The Ethical/Legal Line:
Using these tools can void warranties or raise serious compliance issues within strictly regulated industrial environments. The Recommendation: A Better Way?
Before reaching for a sketchy download, try these steps first: DOPSoft Official Route: Sometimes the "lock" is just at the project level, and Delta's official DOPSoft
might allow for a full reset if you have the original source files. Contact Support: If you have proof of ownership, Delta customer support
or an authorized distributor can sometimes provide recovery paths. Use a Sandbox:
use a third-party unlocker, run it on a dedicated, air-gapped laptop that is never connected to your main industrial network to prevent malware spread.
These tools are a powerful "last resort" for industrial emergencies, but they are a security nightmare. Only use them if the cost of a system-wide lockout outweighs the risk of a malware infection. Do you have a specific HMI model number
(like DOP-B or DOP-100) you're trying to access? Knowing the model can help determine which official recovery options might be available.
deviceTRUST: Boost Citrix Security with Contextual Access Control
Before discussing unlocking methods, it is essential to understand why Delta implements security.
