It is a best practice to encrypt/password protect documents when they contain protected or private information. This will preserve authorized access and make sure only the person(s) authorized can view the information.
- In any office product, in the upper left corner, click File
- Select Protect Document and click Encrypt with Password.
- In the Encrypt Document window, enter a password in the Password field.
NOTE: If the password is lost or forgotten, the document cannot be recovered.
