without-nullok is provided as an authselect feature, so it is enabled on the active profile directly and does not require a custom profile (see the section overview for the authselect profile model). Enable the feature on the active profile: # authselect enable-feature without-nullok Apply the change so that /etc/pam.d/system-auth and /etc/pam.d/password-auth are regenerated without the nullok argument: # authselect apply-changes
