Password Protect Document

This applies to Word, Excel, and PowerPoint documents in Office 2016. Earlier versions may have different ways to protect documents.

When you want to ensure a document doesn’t get changed without your approval, adding a password provides a first-level defence. (There are ways around this constraint, though.)

Note: Make sure you have a backup copy of the document. Useful if you forget the password.

Click File > Info > Protect Document > Encrypt with Password, and enter the password. Click OK.

Removing the password is as simple as deleting what you previously entered.

Note: Besides Encrypt with Password, there is an option to Restrict Editing. This enables you to prevent new styles being created, for instance, or disallow editing.
