You can assign a password to your diagram to keep other users from opening the diagram. You can also request or require that they open the diagram in read-only mode. To assign a password to a diagram and set options that control how much access other users have to the diagram, use File > Diagram Information.
You can assign password protection to specific parts of the diagram. You can also apply protection selectively to embedded diagrams and compound blocks.
Warning: If you decide to use a password to restrict access, make sure to write it down exactly as you entered it — passwords are case sensitive — and store it in a safe place. Without the password, even you cannot access the information.

1. Choose File > Diagram Information.
2. In the Password box, enter a password and select the level of protection you want applied to the diagram.
