Password protect a document in Word for Mac

Password protect a document in Word for Mac

You can protect a sensitive or confidential document by using a password to help prevent others from changing or even opening your document.

You can help prevent unauthorized users from opening a document or from modifying a document even if they have permission to open it. You can also protect your document by specifying how or whether others can leave feedback.

Protect your document from being opened or edited

  1. Click Review > Protect Document.

    On the Review tab, Protect Document is highlighted

  2. Under Security, you can select whether to enter a password to open the document, modify the document, or both. Enter each password again to confirm.

    On the Password Protect dialog box, Security is highlighted

    • Passwords are case-sensitive and can be a maximum of 15 characters long.

    • If you lose or forget your password, Word won't be able to recover it for you. Be sure to keep the a copy of the password in a safe place or create a strong password that you'll remember.

  3. Click OK.

You can help prevent unauthorized users from opening a document or from modifying a document even if they have permission to open it.

Caution: When you create a password for a document, write down the password and keep it in a secure place. If you lose the password, you can't open or gain access to the password-protected document.Passwords in Excel for Mac and Word for Mac have a 15-character limit. You cannot open a workbook or document that has been password protected in the Windows-based version of Excel or Word if the password is longer than fifteen characters. If you want to open the file in Office for Mac, ask the Windows-based author to adjust the password length.

Word doesn't encrypt the data that is hidden in a document. Given sufficient time and knowledge, a user can modify data in any document that he or she has access to. To help prevent modification of data, and to help protect confidential information, limit access to any Word documents that contain such information by storing documents in locations available only to authorized users.
