How 2 Factor Authentication Works

The two-factor authentication gives your account more security by asking you two factors for identifying your identity.

  • Something you can identify such as your username and password or some other Personal Identification Number (PIN).
  • Something you possess such as a smartphone app you can use to verify and approve any request for authentication. Others include a fob or an ATM card.
  • A part of you such as your retina scan, fingerprint, or other biometric that you can also use to authenticate your account.

How to get the factors

  1. SMS Passcodes

  1. Hardware token

With this token, you have the freedom to generate a new passcode whenever you get the prompt for authentication.  If you press a button on the token, it will automatically generate a code you can use for authentication.

  1. Phone callbacks

Pick the call and press any key on the phone to authenticate your account. You will then be given access to the account. By far, this is the simplest form of 2 Factor Authentication.

Conclusion
