The user will be prompted for a password in two situations:
- In the project environment when they attempt to open the Family Types dialog
- When they attempt to open a family file
You can control if you want this check enabled for all Revit family files or not as follows:
- The password will be required to edit and open all family files if there is “AlwaysRequirePassword.txt” file in the BoostYourBIM-FamilySecurity.bundle\Contents folder.
- If this file does not exist, the password will only be required for families that contain an integer parameter named “AccessRestricted” with a value of 1 (or Yes, if you choose to make it a Yes/No parameter)
After the password is successfully entered, the user will not be prompted again for the password during that Revit session. If you purchase a license (for $2.99), a custom password can be set in the pwd.txt file in the BoostYourBIM-FamilySecurity.bundle\Contents folder.
NOTE: This app only protects families when this app is installed. There is no protection when someone without this app attempts to modify families.
