Two-Factor Authentication With TOTP Using Node.js And Speakeasy

Almost two years ago I had written a tutorial around 2FA in a Node.js API with time-based one-time passwords. If you’re unfamiliar, two-factor authentication is becoming the norm, which it wasn’t necessarily back in 2017. If you’re managing user accounts in your web applications, it is critical that you offer your users a second factor of authentication to prevent phishing and malicious login attempts.

While the previous tutorial is still valid, it uses a less popular library to accomplish the task. This time around we’re going to explore using a more popular library called Speakeasy to manage two-factor authentication (2FA) within our Node.js with Express.js application.

Add Two-Factor Authentication To A Golang RESTful API

When it comes to authenticating users for making use of your API, it is a good idea to add an extra step beyond standard username and password. This is called two-factor authentication (2FA) and it acts as a second layer of security for users making use of your application.

Not too long ago I had written about adding 2FA to a RESTful API created with Node.js and Express Framework, but what if we wanted to do it in Golang? The logic isn’t any different, just a new syntax for a new language.

We’re going to see how to add two-factor authentication to a Golang API that makes use of Json Web Tokens (JWT).
