Discussion
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 of several that helps to determine strength and how long it takes to crack a password. The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.
Check Content
