Google has one of the safest tools to verify identity very quickly and easily. This is Google Authenticator, which is automatically activated every time they ask for two-step authentication.

This application works every time you have to provide codes after entering your name and password to confirm your identity, this serves to keep your accounts more secure and is compatible with many other services, such as Facebook, Amazon, etc. Download Google Authenticator for free, you find it available for Android and iOS.

With a very simple interface, its functionality is based on displaying a code consisting of six digits that will be updated automatically every 30 seconds and is the one that you must copy to verify your identity after each login. It works with all the Google accounts you have, and more and more websites and applications accept this type of verification.

Once you have Google Authenticator installed on your phone, you will only have to configure all the accounts to which you want to add this protection, in this way you will not need to do it every time you want to use it. This can be done manually, although the most common is that a QR code appears and you only have to scan it with your mobile phone. This process is the same on practically all the websites that accept it.

This code contains all the necessary information about the account we are wanting to open and its configuration. It includes a secret key that is the one that will generate the 6 numbers that will serve you to enter. For all this process you will not need to have an Internet connection to work.

The other application you are trying to access recognizes that secret key and only has to replicate it to compare it with the one you have entered and see if it is the same. If so, it will quickly confirm your identity and you can start a normal session. Normally it will remember the device you have used and you will no longer need to do this every time you want to log in again.

These are the only steps you will have to do to protect all your personal accounts with two-step verification and for which they will only require the use of a single tool, the Google Authenticator application.
