Setting Up Google Authenticator: A Step-by-Step Guide
Introduction
Google Authenticator is a two-factor authentication (2FA) method that uses a time-based one-time password (TOTP) to verify the identity of users. It is a widely used method for securing online accounts, and setting it up is a relatively straightforward process. In this article, we will guide you through the steps to set up Google Authenticator.
