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.
