DOP B07E415 - Macro password reset

It was an old project created for B07E415 with password for macro's. Now we can't able to restore the password as the developed person was not in our office now. he left without updating the details. is there any possibility to recover the password because we have upgraded the pc software which communicating to that HMI. that changes we need to change in that macro. pls is there any software or process to recover that

If I wanted to hide a password (but make it possible to recover)...
I'd put it in a DLL or preferences file. Maybe in the B07E415 related directory. Maybe in root of hard drive.

Can you locate files with a creation/modification date about the same time the macro was written?

Can you read those files as text using a utility?

Do you spot any sequence of letters that could be a sensible password?

What if you shift letters a step forward in your alphabet? A step backward?
