Google Authenticator is a software designed to manage two-step authentication, developed by the American firm. The two-step check for your Google account allows you to provide an additional layer of security when connecting.
Google Authenticator is a software that protects your account with additional mechanisms. If you connect to your Google account on a third party device, you must enter a code that you will receive via a text message or a Google application. In the application, you will have a double factor authentication code (2 FA), constantly updated that you can use without having sent it by SMS. When you log in to the account, enter this code and the trick is played. This two-step verification system allows you to connect to your Google account by passing not only your password, but by generating a verification code that you can obtain with this application. Google Authenticatorvous grants a 6-digit number that the user must give when authenticating, in addition to its username and password.
Google Authenticator is therefore a guarantee of security against account piracy and software and other malicious viruses. The advantages of an application such as Google Authenticator, besides not seeing his account hijacked, are that you have all the codes in a central location and that they are available all the time, even when your phone is offline.
