Everyone wants his Google account secured from hackers and spammers, and this is the reason that many of you are using 2 step verification process to protect your account. Before moving further let’s have an overview of 2 step verification process. This process is introduced by Google to strengthen the security of Google Account. Now, whenever you sign in to Google, apart from entering your password, as usual, you’ll be asked for a code which is sent to your phone via text/voice call. In this way, it is an added layer of the security for your account. Let’s now move further and imagine a situation where you need to access your account and your phone says “No Network Coverage”. So what next, you cannot access your account as you can only receive the code via message/call. It is a situation of deadlock from which you cannot skip due to the added layer of security. So, it means that this 2 step verification will cause the problem in a zone where your phone has no network? The answer is NO, as Google has also provided a way to get the verification code even though your phone is offline, via Google Authenticator App.
Google Authenticator works with 2-Step Verification for your Google Account to strengthen the security of your account.
