Fix Recommendation

Configure Amazon Linux 2023 to enforce password complexity by requiring that at least one numeric character be used by setting the "dcredit" 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 "dcredit" parameter:

dcredit = -1

Remove any configurations that conflict with the above value.

Check Contents

Verify Amazon Linux 2023 enforces password complexity by requiring that at least one numeric character with the following command:
