Creating an Application Password

In Control Expert, create a password to help protect your application from unwanted modifications. The password is stored encrypted in the application. Any time the application is modified, the password is required.

In addition to the password protection you can encrypt the application files (.STU, .STA and .ZEF). The file encryption feature in Control Expert helps to prevent from being changed by any malicious person and reinforces protection against theft of intellectual property. The file encryption option is protected by a password mechanism.
