Design a design pattern for a two-factor authentication component for web-based systems

I need to design design pattern for 2fa. A good example for two factor authentication 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

Please provide design pattern with:

• Pattern Name

• Intent

• Motivation

• Applicability

• Structure

• Participants

• Collaborations

• Known Uses

• Related Patterns
