As technology has continued to advance, so has the ability of hackers to access our personal accounts and information, potentially putting us at risk of becoming victims of identity fraud or worse. Because of this, internet security has become increasingly important, and many services like Google now take extra steps to help protect consumer’s private data. 

Google Authenticator is an app that uses two-step verification software to keep your information safe by requiring an added layer of identification before allowing anyone to gain access to your accounts. Instead of simply entering a password when logging into Google apps via mobile, Google Authenticator generates a random six-digit code, which you’re required to enter in order to log in if you have two-factor verification active. 

If you’d like to use Google Authenticator to help secure your Google apps, here’s how to do it.
