Add or remove protection in your document, workbook, or presentation

Add or remove protection in your document, workbook, or presentation

In Microsoft Office, you can use passwords to help prevent other people from opening or modifying your documents, workbooks, and presentations. Also, you can use document protection to restrict the types of changes that reviewers can make.

Warning: It's important to know that if you don't remember your password Microsoft can’t retrieve your forgotten passwords.

In this article

  • In an open document, click File > Info > Protect Document.

    • Mark as Final:    Make the document read-only.

      When a document is marked as final, typing, editing, commands, and proofing marks are disabled or turned off and the document becomes read-only. The Mark as Final command helps you communicate that you're sharing a completed version of a document. It also helps prevent reviewers or readers from making inadvertent changes to the document.

      When you mark a document as final, Word asks you to save the file. The next time you open it, you will see a yellow MARKED AS FINAL message at the top of the document. If you click Edit Anyway, the document will no longer be marked as final.

    • Encrypt with Password:    Set a password for the document.

      Important: Keep your password in a safe place. If you lose or forget the password, it cannot be recovered.

      When you select Encrypt with Password, the Encrypt Document dialog box appears. In the Password box, type a password, and then type it again when prompted. Important: Microsoft cannot retrieve lost or forgotten passwords, so keep a list of your passwords and corresponding file names in a safe place.
