Better think twice before choosing a password for e-mail, an online bank or shopping. Simple passwords are easy to be stolen.
A password is like a key to your home. If someone steals it, he'll get chances to steal something. We use passwords everywhere in our life. We are so used to passwords that we don't pay any attention to them until we lose or forget one.
A study of 28,000 passwords recently stolen from a popular website showed that people often did the easy thing. It found that 16% took the first name as a password. Another 14% used the easiest keyboard combinations such as "12345678" or QWERTY. 5% of the stolen passwords were names of television shows or stars popular with young people. 3% of the passwords expressed feelings like "I don't care." "Whatever." "I love you." or their opposite, "I hate you."
Robert Graham, who did the study, advises people to choose a password that is longer than eight characters with one capital letter and one symbol.
Of course, safe passwords don't mean those hard to remember. Forgetting your password is sometimes a big headache for you. Maybe the perfect password is easy for you and hard for others.
