First,make your password out of capital letters(大寫字母).It will be difficult for others to get into your account(賬戶).It only takes a hacker(黑客) ten minutes to work out a six-letter password made of small letters.But the same password in capital letters takes ten hours to work out. Second,add numbers or symbols(符號(hào)) to your password.It may be much safer.Sometimes such passwords are not easy to remember,but they are really safe. Third,never use personal information for passwords and use different passwords for different accounts.Experts say that a user should change his passwords about every 90 days.In that way,hackers won’t guess your passwords.
