Configure RHEL 10 to enforce password complexity by requiring that at least one uppercase character be used by setting the "ucredit" 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 "ucredit" parameter:

ucredit = -1
