IsaacZ 译自 Cisco LEAP 文档
Never write passwords down, on paper or online. Instead, create passwords that you can remember easily but no one can guess easily. One way to do this is create a password that is based on a song title, affirmation, or other phrase. For example, the phrase could be "This May Be One Way To Remember" and the password could be "TmB1w2R!" or "Tmb1W>r~" or some other variation.
永远不要把密码写在纸上或者网上。相反,创建的密码应该自己很容易记忆而别人不容易猜到。一个办法是让密码基于一首歌曲名字或其他短语,比如,可以用短语 "This May Be One Way To Remember",取其首字母,并交叉大小写,数字部分换成阿拉伯数字,就可以生成如下密码:"TmB1w2R!" 、 "Tmb1W>r~" 或者其他变体。
Note: Do not use either of those examples as passwords.
注意:不要使用上面任何一个例子作为自己的密码使用。
