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 option is protected by a password mechanism:

You can help limit remote access to your application and data, regardless of password authentication, by following the Memory Protect instructions (detailed hereafter).
