What is TOTP?
TOTP (Time-based One-Time Password) is a widely used method for two-factor authentication. It generates a new dynamic password every 30 or 60 seconds. The core principle of TOTP relies on synchronizing time between the user’s device and the authentication server. This method offers a high level of security and is difficult to crack.
A popular TOTP tool is Google Authenticator, which produces a 6-digit dynamic code using time and encryption algorithms, providing users with additional account protection.
This guide will illustrate how to set up a TOTP authenticator using Google Authenticator.
