今天收到公司系统提示，又该修改电脑登录密码啦！条件之多，够让人傻20分钟的了。原文摘录如下：

1. Passwords must contain a minimum of 12 characters.
2. Passwords must contain at least 3 of the following 4 characters:
   • At least one lower case alphabetic character (a, b, c, d, e, f, etc.)
   • At least one upper case alphabetic character (A, B, C, D, E, F, etc.)
   • At least one numeric character (1, 2, 3, 4, 5, 6, etc.)
   • At least one special character (comma, period, ?, !, @, #, $, %, ^, &, *, (, ), -, +)
3. Passwords can consist of a "passphrase" - a series of words, such as a simple sentence like, My.2.dogs.are.great! Or, My2dogsaregreat! Passphrases are generally easier to create and remember rather than a long password. 
4. Passwords must be different from the last 6 passwords used.
5. Password cannot include a subset of your first or last name, or a subset of your user account name.

设置这样的密码不容易吧？除了Passphrase，我还有自己的老一个方法：想一句话，近期总想说的话，然后用每个字的首字母，加上大小写和标点符号，就好了。

输入密码也不容易，我被警告了3-4次，才成功！

好消息是，这样的周期性密码修改，从3个月的周期延长至1年了。
