Security settings allow you to set a password for saving changes to the model or opening it. You can also set an expiration date to the project. Note that you can only apply security settings to SMC projects.
To access the security settings in an SMC project:
Open the model.
Click File, then Security Settings.
If the model has already been saved with a password, modifying security settings requires authentication with the Master Password.
To activate the security settings, activate the Use Security Settings checkbox:
Master Password: If you want to apply security settings to the model, it's obligatory to set a Master Password. The Master Password is asked when a user wishes to save changes to a model:
Open password: The opening or master password is asked when a user opens the model:
Saving changes to a model requires the master password.
Expiration Date: Use the drop-down dialog to select a date from the calendar.
If you set an Expiration Date, the model can only be opened after the set date with the Master Password.
Click OK to save the changes.
