Information

Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks.

Password complexity is one of several factors that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that must be tested before the password is compromised.

Solution

Configure the system to require at least one lower-case character when creating or changing a password.

Add or modify the following line
in '/etc/security/pwquality.conf':

lcredit = -1
