Best way to keep google authentication app safe?

[Laxmi Sharma]

We are all know that verifying the account with the google authentication app when using any Exchanger account, greatly ensures the security of the account. So we all use this app.
I think this google authentication app can get lost or crash in any way at any time.
Again, the phone can crash or get lost at any time. So I want to know what is the way to keep the google authentication app safe?
Or is there a way to keep a backup of this google authentication app?

The first time you want to install the 2fa google authenticator security, you must enter the code into the application. This code is the key of your Google Authenticator account, so please save the code/key in your notebook.

Absolutely. As far as I know, the code is the key to be able to access google authenticator. Do not lose  otherwise no chances to open some apps. Better to take note and record the code for the future forgetful moment.

The best way in my opinion is to install the application on a separate phone that you do not use at all, and that you keep it in a safe place, with no connection to the internet, except when you need to use the application.

Nothing to worry about google authentication app if your mobile lost or crash. When you will open 2fa in google authentication then there will show a backup key and you must store that backup key so that if your phone lost or crash you will buy another new phone and enter that code. Your previous google authentication key will work like previous. So be cool.
