What is Two-Factor Authentication (2FA)?

Two-factor authentication (2FA), sometimes referred to as two-step verification or dual-factor authentication, is a security process in which users provide two different authentication factors to verify themselves. It is a combination of two of the following: -Something you know (Your Password). -Something you have (Such as a text with a code sent to your smartphone or other devices) -Something you are (Biometrics using your fingerprint, face or retina)
2FA is implemented to better protect both a user's credentials and the resources the user can access. Two-factor authentication provides a higher level of security than authentication methods that depend on single-factor authentication (SFA), in which the user provides only one factor typically, a password or passcode.
