This article will teach you how to secure a Node.js API by implementing two-factor authentication (2FA) system using tokens generated by Google Authenticator or Authy. The one-time passcode (OTP) can be delivered via different methods like SMS but we will use Google Authenticator or Authy to reduce the complexity of the project.

A small project to fiddle around with two factor authentication in the context of time based one-time passwords also called totp.

In this project, we have created time-based one-time password(TOTP) authentication using Node.js, Express, and Speakeasy.
