To preserve all your hard work—particularly
if others use your files—protect it with a password. You can protect a
sheet or an entire workbook. In each case, you’ll be asked to supply a
password, and then enter it again when you want to work on the file.
Passwords are case sensitive, so be sure to supply your password as it
was first entered. If you forget a password, there is no way to open
the file, so it’s very important to remember or write down your
password(s). Keep your password in a safe place. Avoid obvious
passwords such as your name, your company, or your favorite pet.
