You can assign a password and other
security options so that only those who know the password can open the
workbook, or to protect the integrity of your workbook as it moves from
person to person. At times, you will want the information to be used
but not changed; at other times, you will want only specific people to
be able to view the workbook. Setting a workbook as read-only is useful
when you want a workbook, such as a company-wide bulletin, to be
distributed and read, but not changed. Password protection takes effect
the next time you open the workbook.

Hackers identify passwords as strong or weak. A
strong password is a combination of uppercase and lowercase letters,
numbers, and symbols, such as Grea8t!, while a weak one doesn’t use
different character types, such as Hannah1. Be sure to write down your
passwords and place them in a secure location.
