Set and protect your passwords

Set a password on your computer so only you can access the information on it.

Why this is important

A password is like a lock on your front door; it prevents strangers walking into your house and stealing your possessions.

Using a password and changing it regularly makes it hard for other people to access the information on your computer. When a password is set, your computer will ask you to enter the password whenever you turn it on or (wake it up) from its screensaver. Without the password, it is very hard to access your computer.

Passwords aren’t absolutely unbreakable, but they are a strong deterrent to unauthorised people using your computer.

What you need to do…

1. Avoid passwords that would be readily identifiable or easy for anyone to guess (such as your name or business name)
2. Choose a password consisting of between six and 14 characters
3. Use a mix of upper and lower case letters, numbers and symbols e.g. a very secure password would be something like this: j>kb*D-94x
4. Avoid using dictionary or foreign words because hackers have many tools, such as dictionary programs, to assist them
5. Memorise your password if you can. If you have to record it somewhere don't store it in an obvious place
6. Change your password every month
7. Use a completely new password every time you change your password and never reuse old passwords
8. Never share your password with anyone
9. Never send your password via email.
