Protecting a Document, Workbook, or Presentation with a Password

If your file contains sensitive information that you don’t want anyone else to see, you can encrypt the file so that no one can access its contents unless you give them the password you’ve created. You can further protect the file by allowing access to it but requiring a password to control who may make and save changes to the document, workbook, or presentation.

Encrypt the Document, Workbook, or Presentation

  1. With your document, workbook, or presentation completed and saved, click the Office button, point to Prepare on the menu, and choose Encrypt Document to display the Encrypt Document dialog box.

  2. Enter a password.

  3. Click OK, enter the password again in the Confirm Password dialog box that appears, and click OK.

  4. Make any changes you want, saving the file occasionally, and then close it.

  5. When you want to work on the document, workbook, or presentation again, open it and, in the Password dialog box that appears, enter the password.

  6. Click OK to gain access to the file.
