We use passwords(密码)to keep our personal information secret and safe, but some passwords we use may not be as reliable as we think.

Splash Data, a computer security company, recently released a list of the 25 worst passwords of 2011.This list is based on the research of hackers’ files containing stolen passwords. According to the list, “password” is the worst and most common password. Many others on the list are numbers in order either forward (for example,1234) or backward. Letters on the keyboard in order, such as “qwerty” are also common, as well as some first names and animals. “Hackers can easily break into many accounts(账户) just by trying common passwords again and again, ” said Morgan Slain, CEO of Splash Data.

How can you make a strong password? It should be eight characters or more, with a mix of letters, numbers and symbols. One way to create a long and easy-to-remember password is to separate short words with spaces or numbers. Having safe passwords is necessary for surfing the Internet safely. But it’s not the only thing you must do to keep safety online. Here are some other web safety tips:

●Never give out information that will allow someone to find you offline. That includes your full name, address and phone number.

●Don’t include your real name as part of your online screen name.

●Never meet people you met on the Internet in person. If you insist on breaking this rule, meet in a very public place and consider taking an adult with you.
