Questions: Why are long passwords stronger than short passwords?

The answer is the second one: Long passwords require attackers to make many more attempts to uncover the password.

Explanation for each option:

1. Long passwords always use letters, numbers, and special characters so they are more puzzling to attackers.

   • This is incorrect because the strength of a password is not solely determined by its length but also by its complexity. However, long passwords do not always necessarily include letters, numbers, and special characters.

2. Long passwords require attackers to make many more attempts to uncover the password.

   • This is correct. The length of a password increases the number of possible combinations exponentially, making it significantly harder for attackers to guess or brute-force the password.

3. Short passwords take up less storage space which makes them easier to break.

   • This is incorrect. The storage space required for a password does not impact its strength or the difficulty of breaking it.

4. Long passwords are confusing to attackers who cannot read them.

   • This is incorrect. Attackers typically use automated tools to crack passwords, and the readability of the password is not a factor in its strength.

Summary: Long passwords are stronger because they require attackers to make many more attempts to uncover the password due to the increased number of possible combinations.
