Description
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Use of a complex password helps to increase the time and resources required to compromise the password. The more complex the password is, the greater the number of possible combinations that need to be tested before the password is compromised.
