Description
Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. Password complexity is one factor of several that determine how long it takes to crack a password. The more complex the password is, the greater the number of possible combinations that need to be tested before the password is compromised. Use of a complex password helps to increase the time and resources required to compromise the password. The PSWD GSO record values specify the rules that ACF2 will apply when a user selects a new password. Improper setting of any of these fields, individually or in combination with another, can result in weakened passwords and compromise the security of the processing environment.
