Two-factor authentication

Implemented the simple API of a simple two-factor authentication solution using Node.js (express) with TypeScript..

The simple API has the following features:

• Ability to create a six-digit authentication code (one-time password, OTP) that expires after a predefined amount of time, say 60 seconds.
• Ability to send via SMS the above authentication code to a phone number. For now, I am just showing it on the console on the backend. Please check api server logs to see this code.
• Ability to validate the authentication code with the one entered by the user.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
