Fix Recommendation

Configure OL 9 to enforce password complexity by requiring at least one numeric character is used by setting the "dcredit" option.

Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value):

dcredit = -1

Check Contents

Verify that OL 9 enforces password complexity by requiring at least one numeric character.

Check the value for "dcredit" with the following command:

$ grep dcredit /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf
/etc/security/pwquality.conf:dcredit = -1
