Password protecting a Word file is a great way to add an extra layer of protection to your documents with sensitive data inside.
Word has a built-in password protection system you can use to quickly and effectively protect your files.
To password protect a Word document, open the document and select File, Info, then Protect Document. Choose Encrypt with Password and enter your desired password.
If you don't have Word, you can use the online version for free or subscribe to Microsoft 365 for access to all Office apps.
