Design a design pattern for a two-factor authentication component for web-based systems. Define the design pattern using the elements below of the design pattern description as define by the Gang of Fours Design Patterns. Two-factor authentication is a technology patented in 1984 that provides identification of users by means of the combination of two different components. These components may be something that the user knows, something that the user possesses or something that is inseparable from the user. A good example from everyday life is the withdrawing of money from a cash machine. Only the correct combination of a bank card (something that the user possesses) and a PIN (personal identification number, i.e. something that the user knows) allows the transaction to be carried out (from https://en.wikipedia.org/wiki/Two-factor_authentication).
