1NF: First Normal Form - Eliminate repeating data and non-atomic values; add keys The data is stored in a relation (table) and each attribute (column) contains atomic values. There are no repeating groups of attributes. 2NF: Second Normal Form - Eliminate partial dependencies. The relation is in fırst normal form and all the attributes depend on the relation's unique identifier (primary key). --All the nonkey columns are dependent o the table's primary key. (All nonkey attributes are functionally dependent on the entire primary key.) 3NF: Third Normal Form - Eliminate transitive dependencies. The relation is in second normal form and all of its attributes are not transitively dependent on the unique identifier. ----A table contains only columns that are non-transitively dependent on the primary key (i.e., all nonkey attributes depend only on the primary key)

We tell people and tell people not to use words from the dictionary as password, but they just don't listen . . . Can you find this one word, three-letter, bad password? By the way, this challenge is not really meant for you to manually guess!

Could you please describe the idea of a challenge-and-response authentication system to me in your own words so that I can fully grasp it? (CRAS). What about this technique of authentication is more secure than using a password?
