How do I password protect a Word or Excel document?
Word and Excel both allow you to password-protect individual documents. When you password protect a document, no one can open or edit that document without first entering the correct password. This is a good way to keep other people from reading your personal documents.
Please be aware, however, that this type of password protection does not protect your files against accidental or intentional deletion! If you are concerned about a roommate deleting your personal files, then you should keep backup copies of those files on floppy or zip disks.
To password protect a Word or Excel document:
Go to the File menu and choose Save As.
In the Save As dialog, click Tools and choose General Options.
Type a password in the Password to Open box and click Ok. Don't worry about the Password to Modify box--this is for business users who want to distinguish between users who are allowed to read a document and users who are allowed to change a document.
Confirm the password. Read the warning in this dialog before you click Ok!
Password protection operates on a per-document basis. Thus, you will need to set a password individually for each document you want to protect. You can use the same password for more than one document, but you'll still have to set it manually for each document.
