What term describes passwords that use uppercase and lowercase letters, numbers, and symbols?

• A. Secure passwords
• B. Tailgating
• C. Shoulder Surfing
• D. Spear fishing

Answer: (A)

Password strength comes from complexity and higher entropy. A password that uses a mix of uppercase and lowercase letters, numbers, and symbols increases the number of possible combinations, making it much harder for attackers to crack it by brute force or guessing. That makes secure passwords the best description for this scenario. The other terms point to different security concerns: tailgating is when someone unauthorized follows you into a restricted area, shoulder surfing is watching someone enter a password, and spear phishing is a targeted attempt to obtain credentials. So the best answer describes the protective quality of the password itself.
