Nowadays, computers and Internet are playing an important part in our life. We usually need to set passwords(密码) when we use computers and Internet. In order to keep our accounts (账户)and personal information safe, we must learn how to set safe passwords.

Experts have some useful advice for you. You’d better remember them. First, make your password out of capital(大写的)letters. It only takes a hacker(黑客)10 minutes to work out a 6-letter password made of small letters. But the same password in capital letters takes 10 hours to work out. Second, add numbers or symbols to your password. It may be much safer. Third, never use personal information for passwords and use different passwords for different accounts. At last, a user should change his or her passwords every 90 days. In this way, hackers won’t guess your passwords.
