Description
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 determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that needs to be tested before the password is compromised. Typically, the account of last resort is a built-in account with full privileges to the network device. This account should only be used when the authentication mechanism is unreachable and configuration or maintenance actions must be taken.
