Bypassing a password set by an OEM or system integrator may violate intellectual property laws, invalidate equipment warranties, or breach service-level agreements. Official and Safe Methods to Recover Access
Some older units may also respond to 888888 . 🛠️ 2. Official Software & Connection
You may encounter third-party tools claiming to "crack" or "read" Delta HMI project passwords from .DPS , .DPA , or .DOP files.
The safest, fastest path to obtaining the password is contacting the Original Equipment Manufacturer (OEM) who built the machine. Most integrators keep master backups of the uncompiled project files ( .dpb or .dps ). They can provide the original project file directly, bypassing the need to upload from the physical HMI. Check Default Passwords Delta Hmi Password Unlock Software
If you have an old DOP-B series HMI and have accepted the risks, here is the typical workflow for a third-party unlock tool:
The typical process involves:
Delta uses proprietary hashing algorithms to store passwords. When you set a password in DOPSoft (Delta’s configuration software), the HMI stores a hash, not the plain text. A legitimate unlock process does not "crack" the hash instantly; instead, it either removes the password flag or utilizes a backdoor method provided by the manufacturer. Bypassing a password set by an OEM or
Some aggressive tools do not recover the password; instead, they wipe the security layer. This is highly risky, as it can inadvertently corrupt the runtime application or brick the HMI screen entirely. Common Tools Available on the Market
Reach out to the company that built the machine. Even if the machine is out of warranty, they often maintain an archive of project files and passwords indexed by the machine’s serial number. Phase 3: Official Delta Technical Support

The utility opens the Delta HMI project file in a binary/hexadecimal format.
Reading the hex data directly from the HMI’s physical memory chips using an external programmer, then searching for specific data strings.
Restricts access to specific screens, calibration settings, or supervisor menus on the physical machine.
Stops unauthorized changes to the machine's operational screens.
A: Free tools exist for obsolete DOP-A series, but they are unreliable. For DOP-B and DOP-100, truly free tools are almost always malware. Expect to pay a specialized service $100–$500 for a remote unlock.
