If an account that is protected by a password gets cracked then you should be more careful with choosing passwords. Passwords should contain uppercase and lowercase characters (e.g. a-z, A-Z) and have digits (0-9) and punctuation characters and symbols (`~!@#$%&*()-_=+[]{}\;:'",.<>/?) and the length should at least be 8, but better is a length of 12 or more. Never use words that can be found or constructed via a dictionary look up, even if there are numbers added or some characters have a different case. * https://support.mozilla.org/kb/create-secure-passwords-keep-your-identity-safe * http://en.wikipedia.org/wiki/Password_strength ---- It is possible that you have a virus or malware on your computer, so you should check for that as well.
