According to Wikipedia, a one-time password (OTP) is a password that is valid for only one login session or transaction. It is also known as a one-time PIN, one-time authorization code or dynamic password. OTP has become popular because it is one of the most secure ways to verify user identity before login or password recovery. However, implementing such a feature in your application can be challenging. In this post, I am happy to show you how to generate and verify OTP easily within Total.js Flow.
