API with NestJS #31. Two-factor Authentication - We go through the principles of two-factor authentication and put them into practice with NestJS and Google Authenticator.
While developing our application, security should be one of our main concerns. One of the ways we can improve it is by implementing a two-factor authentication mechanism. This article goes through its principles and puts them into practice with NestJS and Google Authenticator.
