Question

Nowadays, computers and the Internet are playing an important part in our life. Some people even say that they can’t live without them. We usually need to set passwords (密碼) when we use the computers. But not all the passwords are safe. We should learn how to make safe passwords.

How can you make your passwords safe? Experts have some tips for you. You’d better remember the tips because they are useful. Here are some tips.

First, make your password out of capital letters. It will be difficult for others to get into your account (賬戶). It only takes a hacker (黑客) 10 minutes to work out a six-letter password made of small letters. But the same password in capital letters takes 10 hours to work out.

Second, add numbers or symbols (符號) 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.
