Define a strong password and list at least three best practices for password security.

• A. A strong password is short and simple; use predictable words.
• B. A strong password is the same as your username; reuse across sites.
• C. A strong password is long, complex, and unique; best practices include using 12+ characters with upper/lowercase letters, numbers, and symbols; avoiding common words; enabling multi-factor authentication; and using a password manager.
• D. A strong password is always numeric.

Answer: (C)

Strong passwords rely on length, unpredictability, and uniqueness to resist guessing and cracking. A good approach is to use a password that is long (12 or more characters) and uses a mix of uppercase and lowercase letters, digits, and symbols, while avoiding common words or predictable patterns. Enabling multi-factor authentication adds an extra hurdle for anyone trying to access the account, even if they obtain the password. A password manager helps you generate and store these complex, unique passwords securely, so you don’t have to memorize them all. Short or simple passwords are easy to guess or brute-forced; using your username as part of a password or reusing the same password on multiple sites creates multiple points of failure; numeric-only passwords lack the variety needed to withstand attacks.
