You can assign a password and other security options
so that only those who know the password can open the presentation, or
to protect the integrity of your presentation 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 presentation. Setting a presentation as read-only is useful
when you want a presentation, such as a company-wide bulletin, to be
distributed and read, but not changed. Password protection takes effect
the next time you open the presentation.

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 different location.
