忘记了设置的冗长密码？害怕账户被黑？所有这些烦心事将成为历史，因为研究表明，只要将密码字母全部改为大写形式，账户被黑的几率就会大大降低。

《商业周刊》 数据显示，黑客只需用10分钟即可破解6个小写字母组成的密码。但若是大写字母密码，黑客就得花掉10个小时来破解。如果在大写字母中添加数字和（或）符号，18天之内你的账户会安然无恙。

另外，选择一个由9个字母组成的密码并添加了数字和（或）符号，会花掉黑客44530年才能成功破解。

然而，目前还是有一半的人只用一个普通字母或者简单的字母组合作为密码，而最常用的密码便是123456，password（密码），12345678，qwerty（键盘）以及abc123。

Forget your unwieldy passwords? Worry about being hacked? All this nuisance would become history, since researchers have found that simply by upper-casing your password you can minimize a hacker's chance of breaking into your account.

A six-letter password in lower-case text takes a hacker's computer just ten minutes to crack, according to statistics collated by Bloomberg Businessweek. But make those letters upper-case and it takes ten hours. Add numbers and/or symbols to your password and the hacker's computer has to work for 18 days.

If you choose a nine letter password that includes numbers and/or symbols would take a hacker's computer a staggering 44,530 years to break.

However, 50 percent of people choose a common word or simple key combination for their password. The most used passwords are 123456, password, 12345678, qwerty and abc123.
