Two-factor authentication (2FA) and multi-factor authentication (MFA) are essentially the same thing. They are used to improve the security of our information by requiring us to provide two or more “factors” of authentication to prove who we are.
There are three main factors: what you are, what you know and what you have.
Username and password are an example of what you know. However, if your password is stolen, someone can impersonate you.
Therefore, a second factor, such as sending a code to your phone or using a fingerprint, can help secure our authentication.
Now an attacker would have to compromise several elements to impersonate you.
