The solution is straightforward and explicitly stated in Pilz documentation: Change the default password during project finalisation . Best practices include:
Full access to software configuration, hardware layout, safety logic editing, chip card burning, and user management.
Open the PNOZmulti Configurator on your programming terminal.
Lock the control cabinets housing the PNOZmulti units. Since anyone with physical access can pull out the chip card and attempt to overwrite it, physical restriction acts as your first line of defense. pnozmulti configurator default password
You must format or replace the chip card, completely erasing the encrypted data.

If authorized, perform a or re-download a known good configuration to the PNOZmulti hardware, which will override the existing password protections. Best Practices for PNOZmulti Security
If you encounter issues with the PNOZmulti configurator default password, here are some common problems and solutions:
Securely store master copies of your .pzad or .pzp configuration files on a password-protected engineering workstation or an offline backup server. Lock the control cabinets housing the PNOZmulti units
Understanding why passwords exist in a safety context is critical. This is not about keeping trade secrets (though that is a secondary benefit). It is about (ISO 13849-1, IEC 62061).
"The product is not protected from physical manipulation or from reading of memory contents during physical access. Use appropriate measures to ensure that there is no physical access by unauthorized persons. You should also use security seals so that you can detect any manipulation of the product or interfaces. Installation inside a lockable control cabinet is recommended as a minimum measure."
You must prove ownership of the machine. Pilz support may guide you through a reset process, but they will not "crack" or recover the password. They may require a purchase order or serial number verification.
