Ubuntu 使用者の暗証番号を短くて設置する方法

Posted at

面倒すぎるので、とりあえず短い暗証番号が欲しいですが、短すぎるで出来なかった。
解決方法をここでメモします。

やり方

sudo vi /etc/pam.d/common-password

下記の行で minlen=n を追記します
例えば、最小桁3に設置します

/etc/pam.d/common-password
...
# here are the per-package modules (the "Primary" block)
password        [success=1 default=ignore]      pam_unix.so obscure sha512 minlen=3
...

それからpasswdコマンドで設置できます

sudo passwd username
