2.What is a brute force attack? 3. Why are rainbow table attacks superior to brute force? 4. What is a hash and what is its relevance to passwords?

5. What is a seed and how is it used in password storage protection? 6. Describe the benefits of 2-factor authentication and provide at least two examples.
