 由于粗心地或处理选择密码，会危及密码的安全。由于这个原因，您不应该选择出现在词典中或者必须要写下来才能记住的密码。密码也不应该是一个名字、许可证号、生日或者街道号。所有这些可以用于猜测来损害系统安全。

+As a general guideline, passwords should be long and random\&. It\*(Aqs fine to use simple character sets, such as passwords consisting only of lowercase letters, if that helps memorizing longer passwords\&.
