How do you protect a document with a password in MS Word?

Click File, then Info, then Protect Document, and choose Encrypt with Password. This adds password protection so only people with the password can open the file. You’ll need to enter the password twice to confirm it.

The Home tab handles formatting, not security. Insert adds content to documents. Review checks spelling and tracks changes.

File menu contains document management features. Security settings like password protection live there along with saving and printing options.
