Fix Recommendation

Configure RHEL 10 to enforce password complexity by requiring that at least one lowercase character be used by setting the "lcredit" option.

Add or update the following line in the "/etc/security/pwquality.conf" file or a configuration file in the "/etc/security/pwquality.conf.d/" directory to contain the "lcredit" parameter:

lcredit = -1

Check Contents

Verify RHEL 10 enforces password complexity by requiring that at least one lowercase character be used with the following command:

$ sudo grep -s lcredit /etc/security/pwquality.conf /etc/security/pwquality.conf/*.conf
/etc/security/pwquality.conf:lcredit = -1

If the value of "lcredit" is a positive number or is commented out, this is a finding.
