Life password is the password that you use for every website, email account, social networking website, micro-blog, and everything. Having a 'life password' is not a good idea, but everyone does it.

“生活密码”指你登陆任何网站、电子邮件、社交网站、微博等等所有帐户时使用同一个密码，即“通用密码”。使用“生活密码/通用密码”并不是明智之举，但是很多人都在这样做。

For example:

My friend found out my life password and wrecked¹ my Facebook account, stole all my paypal money and emailed offensive images to my mother.

我朋友知道了我的通用密码，然后就擅自进入了我的Facebook账号，偷了我贝宝帐户里所有的钱，还给用我的邮箱给我妈妈发了几张不雅的图片。
