Changing Your Password
One of the best ways to prevent others from using your account is to change your password occasionally—especially if you’ve given it to someone or you suspect that someone might have guessed it or watched you type it. When you change your password, create one that can’t be easily guessed (don’t use "password" or your well-known nickname, for example), and try to incorporate both uppercase and lowercase letters as well as one or two numbers. Of course, don’t make the password so complicated that you can’t remember it!
