Which password characteristic is least desired in a secure system?

• A. Complexity
• B. Length
• C. Repetition
• D. Diversity of characters

Answer: (C)

In the context of password security, repetition is the least desired characteristic in a secure system. Repetitive patterns in passwords weaken their strength, making them easier to guess or crack through brute-force attacks or dictionary attacks. When users create passwords that repeat characters or patterns (such as “abcabc” or “111111”), it reduces the overall entropy and randomness of the password. A strong password should ideally be complex, lengthy, and diverse in character types, meaning it should include a mix of uppercase letters, lowercase letters, numbers, and special characters. These characteristics help create a more unpredictable password, enhancing its resistance of against unauthorized access. In summary, while complexity, length, and diversity of characters contribute positively to password strength, repetition creates vulnerabilities, making it the least desirable characteristic in a secure system.
