登录密码不够好

Joh*_*ose 5 password login 16.04

我尝试使用 User 形式的小写和大写字母后跟数字来设置登录密码(其中 User 是我的用户名,因此密码至少由 8 个字符组成)。我也试过用数字缩写。我不断变得不够好。我一直无法找到一套明确的登录密码规则。谁能给我指出一套明确的登录密码规则?

如果您对安全性没有真正的兴趣,您可以通过让系统自动登录来避免输入密码

但是,如果您确实需要安全密码(在大多数情况下这是明智的),则建议遵循以下准则。

Strong Passwords

Applications, and libraries exist for your Ubuntu system to assist in generating, or enforcing strong passwords. A strong password is defined as any password which meets the following criteria:

    At least fifteen (15) characters in length.
    Does not contain your user name, real name, organization name, family member's names or names of your pets.
    Does not contain your birth date.
    Does not contain a complete dictionary word.
    Is significantly different from your previous password.

    Should contain three (3) of the following character types.
        Lowercase Alphabetical (a, b, c, etc.)
        Uppercase Alphabetical (A, B, C, etc.)
        Numerics (0, 1, 2, etc.)
        Special Characters (@, %, !, etc.)

编辑:如果您想强制执行强密码或放宽密码要求,所有这些都可以通过编辑进行配置/etc/security/pwquality.conf该文件被大量注释并且非常不言自明。有关各个选项的详细信息可以在手册页上找到

默认情况下,Ubuntu 要求密码长度至少为 6 个字符,以及一些基本的熵检查

所以应该没问题。如果您有权访问,/etc/pam.d/common-password您可以评论一个词“TEMPORARY”并使用它,直到正确设置您的帐户。(如果你不喜欢的话我推荐一张live CD)
