Security Options Dialog Box

Specifies security settings to be used when your drawing is saved.

List of Options

The following options are displayed.

Password Tab

Adds a password to a drawing when the drawing is saved (not available in AutoCAD LT).

Important: The ability to add a password to a drawing will be removed in the next release because it does not meet contemporary security standards. You will continue to be able to open password-protected files.
Password or Phrase to Open This Drawing

Adds, changes, or removes a password the next time the drawing is saved.

If you add or change the password, the Confirm Password dialog box is displayed. If you lose the password, it is not recoverable. Before you add a password, you should create a backup copy that is not protected with a password.

Encrypt Drawing Properties

Drawing properties are details that help you identify the drawing, including title, author, subject, keywords that identify the model, or other important information.
