As our lives become more connected to the internet, the risk of exposure to online threats also increases. It doesn’t matter how tight your security is; hackers will still find a way to sneak into your online accounts.

While you can’t avoid all sorts of hacking events, certain things are in your hands to improve the security of your online accounts. When protecting online accounts, passwords used to be a thing of the past. These days, security experts set up 2FA on every online account.

2FA or two-factor authentication is basically an extra layer of security over existing SFA or single-factor authentication (username & password). The two-factor authentication uses the traditional username/password as the first factor, and the second factor is the temporary passcode sent as an SMS or received via an authenticator app like Google Authenticator.

What is Google Authenticator?

Google Authenticator is basically a security app from Google that lets you generate 2FA codes for your added sites or services.

When you use the Google Authenticator app, the codes are available in-app instead of through a text sent to your registered phone number.

The benefit of using Google Authenticator for generating codes is that the app can generate codes without internet or mobile services. The advantage of using 2FA apps over SMS-based Verification is that you can receive the codes even when your phone has no cellular services.
