The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.


Configure the Ubuntu operating system to enforce a minimum 15-character password length.

Add or modify the 'minlen' parameter value to the '/etc/security/pwquality.conf' file:
