Controlling Your Computer Accounts
Your computer’s physical security, as well as online security, depends on how
easy it is to access your accounts. This topic shows you many ways that you can
protect your computer, but almost all of them can be defeated by an account
on your computer that has a poor password or no password at all. This is why
it is critical to ensure that your computer is protected by accounts with strong
passwords. Anything less will weaken your entire security defense.
This section shows you how you can manage your user accounts in Windows 8
to make sure they are all well protected.
Using Complex Passwords on All Your Computer Accounts
All the accounts on your computer should have a complex password associated
with them in case your computer is ever exposed to the Internet. Passwords
such as easy-to-remember words and predictable key combinations, such as
“asdf,” just don’t cut it. These types of passwords are vulnerable to brute force
dictionary attacks where an intruder can use special software to try hundreds
of combinations to hack into your account.
A complex password is a password that has at least eight characters and
consists of uppercase and lowercase letters, as well as numbers or other symbols.
Ftm3D8&- is an example of a complex password. Something such as this is very
difficult to guess and will take quite some time for a brute force technique to
crack it.
Using complex passwords on all your accounts might not be easy at first, but
after a while they will grow on you and you will have no problem remembering
them. To prevent losing access to any encrypted files, it is best to log on to each
account that does not already have a complex password and change them. If
you use the Set Password function in Computer Manager, you risk losing access
to any files that were encrypted under the user’s account.
Follow these steps to safely change a user’s account password:
1. Log on to the users account that needs a password change.
2. Press and hold Ctrl+Alt+Delete so that the secure desktop is shown (see
Figure 18-6).
3. Click the Change Password button.
4. Type the old password once and then the new password for the user twice,
and click the blue arrow button.
