Description
The minimum password length must be set to 15 characters. 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. The use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.
