Encrypt a Microsoft Word Document

If you have a MS Word that contains sensitive information, you can password protect the document so that it can be safely transmitted via email or stored in a network file share. Be careful to not lose or forget the password as the document cannot be opened without it.

Step-by-step guide

To encrypt and password protect your document, follow these steps in Microsoft Word

  1. Open the doc you want to protect.

  2. Choose File > Info > Protect Document.

  3. Select Encrypt with Password.


  4. The Encrypt Document dialog box appears; type your password into the text box and repeat when prompted.

  5. Save your document - it is now encrypted and password-protected.

If you're sending the protected file to someone via email, be sure to provide the password to the recipient through a means that is not email such as a phone call or text message.
