Google's 2-Step Verification service, for example, involves the usual password (something the user knows) and a code sent to the user's device (something the user has). Nevertheless, many two-step verification products and services are also examples of two-factor authentication. ![]() Authentication is considered an adaptation of verification processes designed to protect automated and online systems. Verification can be part of a real-world process - providing a driver's license as proof of identity, for example. However, in contrast with 2FA processes, the methods in two-step verification can belong to the same category of authentication factors, and the methods used for 2FA aren't necessarily sequential.įurthermore, verification and authentication are not completely synonymous. Two-step verification is sometimes confused with two-factor authentication ( 2FA), which also involves two usually sequential methods used for verification. The difference between two-step verification and two-factor authentication: Two-step verification is a process that involves two authentication methods performed one after the other to verify that someone or something requesting access is who or what they are declared to be.
