台媒：研究称定期换密码更容易被破解 - 密码 - IT资讯

台媒称，许多网站呼吁民众应经常更换密码增强被害的可能，但近期有专家指出，定期更改密码，不一定能提高安全性，反倒让帐号更容易破解。

据台湾中时电子报3月8日报道，研究实验指出，专家指定一些学生定期换密码，不久后他们会感到厌烦，而将密码越改越简单，导致密码被破解的机率会较其他人设定的高出46%。因为这些人，大部分会利用最初的密码，把数字或字母换个位置，或增加一两个字元。比如用户会将“secret10jan”改为“secret10mar”。若骇客知道使用者以前的密码，那么他们就有41%的机率于3秒内破解新密码。

所以专家呼吁，这不代表不需定期更改密码，而是要使用完全不同的密码，这样才能增加帐户的安全性。
