• DragDrop: Allows the user to drag and drop words from a word bank into the correct box. Author can change box titles, words in the word bank, and decide what box each word should go into.
• PasswordChecker: Allows the user to type into an input box that checks if a password passes all requirements. Requirements can be changed/deleted, but requirements can't be added.
• FixPassword: A number of weak passwords are given, and each password should be changed into a strong password. The number of passwords given can be changed, as well as what the passwords are.
