Two factor authentication is a way of verifying a user’s identity using two factors: 1) something they know, 2) something they have. It’s a second layer of security to ensure that no one can access your account. You can think of it as a second password.
If you have a bank account and used online banking, then you have used Two factor authentication. It’s the code that is sent to your phone to verify your identity. This is just one way of getting that code, out of five.
The other way is by using a Two factor authentication app. An example of that would be 1Password, Authy or Google Authenticator. Services like Google, MailChimp and Lightning Base allows you to pick an app as your authentication method.
You can also get the code by an automated phone call, an email or by a hardware token such as the RSA SecureID.
