Would you tell others your QQ password (密码)? Of course not. But if your passwords are too easy, hackers(黑客) can guess them.

These days we have too many passwords to remember. To make life easy, some people use simple passwords, like123456, “888888”or “abc123”. Many also use personal information (个人信息), such as a birthday, as passwords.

But these easy passwords are not safe online. Here are some tips for a safer password.

Upper-casing (大写) your password is a good start. Put numbers and symbols (符号) in your password. Don’t use words you can find in a dictionary (词典). Make your passwords long.

For example, make a password of nine letters, with numbers and symbols in it. Then it will take hackers hundreds of years to work out!

Never use personal information as a password, Use different passwords for different things. Change your passwords every 90 days.
