How to Choose a Strong "Password"

When choosing a password remember these points

1. Don't use characters that are of personal significance 
2. Mix letters, numbers and symbols, and use case sensitivity. Using this, it is almost impossible to "crack" somebody's password. ( instead of "password," try "pAsS34%(6*2woRd," etc.)
3. Find a good way to remember. A good way to do this is to choose the first letters of a sentence that you will remember. e.g. "I have 2 dogs called Rover and Fido" gives: Ih2dcRaF
4. Try to memorize the password, and avoid writing it down. Somebody could very easily find the slip of paper that the password is written on.
