Picture the scenario.

You use dropbox and store all your personal files in it. You have a complex long password and all is well. Later you read in the news that dropbox suffered a data breach and 2 million usernames and passwords were stolen. Maybe, like millions of other internet users, you use that same username and password with another service.  Suddenly, that complex, long password is useless and your data has now been compromised.

This is were two factor authentication (2FA) comes to in.

Without baffling you with jargon, simply put, two factor authentication means your password alone will not allow someone (even you) to log into an internet account that supports it. You’ll need two forms of authentication, your password, and a one time code provided by the Google Authenticator App on your phone, and you’re the only one that has access to your phone.

Many important internet services support two factor authentication and it’s important that you start using it.  Think about your online email account for example.  Just think about how many emails you’ve received over the years that contain sensitive personal and identifiable information. Imagine if someone was able to hack into your account using a password that’s been compromised from breached website.
