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 determine strength and how long it takes to crack a password. Use of more characters in a password helps exponentially increase the time and/or resources required to compromise the password.


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

Edit '/etc/pam.d/common-password' and edit the line containing '' to contain the option 'minlen=15' after the third column.

The DoD standard requires a minimum 15-character password length.
