While 2FA may be an unfamiliar term, you are most likely using it every day. A good example of 2FA would be when using your ATM or debit card. Every time you are asked for your pin or zip code, you are providing a second type of authentication. 2FA is a combination of information used to verify your identity. These factors are usually a mixture of something you know, like a pin number or a password. Something you have, like your debit card or key card for an office door. Or something you are, like your fingerprint.
By implementing 2FA for your email address or system account, you add a significant layer to your overall security. The 2FA process usually works like this:
Step 1: Sign in using a username and password.
Nothing changes here. You would login like normal to your email or system account. You are then routed to a new page that prompts you for the second form of authentication.
