Google Authenticator is an application available for Android and iOS, created by Google. The purpose of this application is to provide codes that will be used in two-step verification . Therefore, it helps the user to identify or verify their identity in any application or account they have. After entering the username and password, you are asked to enter a code, which is sent to this app.
This application is compatible with many services . Of course it can be used with Google’s own, in those applications or services where it is needed. In addition, it can be used with other applications or services, such as Facebook, Instagram or Amazon, among many others. Compatibility with so many services makes it a very reliable option.
Google Authenticator is an application that we can download on any Android phone for free . The application is available in the Play Store, you can download it here below. Thus it will be possible to use it at all times in two-step authentication on various accounts or platforms.

The first step we have to complete is to choose the account we want to protect, which in this case could be our Google account. The application gives two options in this case: Carry it out manually or scan a QR code where all the account information is. Each user can choose the desired option, although the code is much simpler and faster. Then we scan the code in question.
We can now log in to a web page or application , entering the username and password. Next, the code shown on the screen in Google Authenticator must be entered on that website or application. By entering this code the verification is completed in two steps, it is known that we are, so that we have access to said application or said web page in question.
When we use this identification service, we will see that the codes displayed on the screen change every few seconds . Therefore, there are times when when we start introducing it, it changes to a different one, the frequency is somewhat variable, but we must be prepared for this situation, since it is something that can happen to us on occasion.
