If multifactor authentication is not supported and passwords must be used, the HP FlexFabric Switch must enforce password complexity by requiring that at least one lower-case character be used.

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