A good password is your key to proper security. They are used all over the place. First, to log on to your computer, to access your email, to log in to your banking site etc. It is important that you use good sense in selecting them. Most  organizations, like banks, have special rules; what can and cannot be used, how many characters, upper and lower case, numbers and more.

Here is a short list of what to use...
  • A minimum of 8 characters
  • At least 1 upper case and 1 lower case
  • At least 1 number
Use even more if you like. Also you can use certain punctuation characters like ! # and others. Some will not be allowed and you will be told so if you try. Make your passwords "strong." Some things not to use...
  • Any names associated with you or your family
  • Telephone numbers and addresses
  • Be careful using "favorite places"
And never use any of the following...
  • Password
  • Passwd
  • admin
  • login or logon
  • qwerty (most will not allow this)
  • 1122333 - multiple same character (most will not allow this either)
The never use versions are the first a hacker will try.

Try not to use the same password for multiple sites. If one is hacked, the hacker will have access to the others. This is also one of the first things the hacker looks for.

It is good practice to periodically change passwords. Maybe ever 6 months or year. A site with good security will not allow you to re use a password that you used previously on that site.
