You can hide or show your passwords on your documentations, metadata, contexts, and so on when they are stored in the Repository tree view.
To hide your password:
On the toolbar of the Studio main window, click or click File > Edit Project Properties from the menu bar to open the [Project Settings] dialog box.
In the tree view of the dialog box, click the Security node to open the corresponding view.
Select the Hide passwords check box to hide your password.
If you select the Hide passwords check box, your password will be hidden for all your documentations, contexts, and so on, as well as for your component properties when you select Repository in the Property Type field of the component Basic settings view, as in the screen capture below. However, if you select Built-in, the password will not be hidden.
In the [Project Settings] dialog box, click Apply to validate your changes and then OK to close the dialog box.
