Resolve and Remove “BAD PASSWORD: it is based on a dictionary word “in Linux
If you know what you’re doing and want to use weak password in Linux (CentOS, RedHat … etc), follow the steps below.
- vi /etc/pam.d/system-auth as root.
- Look for the following two lines:
password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok
按提示打开文件:

1. password requisite pam_cracklib.so try_first_pass retry=3
2. password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok
3. Comment out the first of the two lines: 注释掉此行
#password requisite pam_cracklib.so try_first_pass retry=3
4. Remove use_authtok on the second line. Otherwise you’ll get “passwd: Authentication information cannot be recovered” error.
删除掉 "use_authtok “从第二行,否则你会得到"passwd : Authentication information canot be recovered "的错误提示
password sufficient pam_unix.so md5 shadow nullok try_first_pass
5. That’s it. Try changing your password again.
