How strong is your password?
Make your passwords hard to guess - Try not to use things like your name, birthday, pet's name etc that would be easy for someone else to guess.
Make them as long and complex as possible (but don't forget them). If you use at least 14 characters and mix letters, numbers and special characters it will be harder to guess. Combining several unrelated words or phrases is good too.
Try not to use the same password for everything - if someone guesses your password they may try it with other accounts.
