Adding Security Encryption to a Document
File encryption is additional security you can apply to a document. File encryption scrambles your password to protect your document from unauthorized people from breaking into the file. You don’t have to worry about the encryption, Word handles everything. All you need to do is remember the password. If you forget it, you can’t open the file. Password protection takes effect the next time you open the document. To set password protection using file encryption, select the File tab, point to Prepare, select Encrypt Document, enter a password, write it down for safekeeping, and then reenter the password again. Password protection takes effect the next time you open the document.
