To create one, user must use a variety of symbols that include both lowercase and capital letters, numbers and special characters. In addition to that a password must be at least 12 characters long – the shorter it is the faster it is to crack. It is recommended to create a unique password for each service and use a password manager that could store all the unique passwords.
