The second time is to confirm the password. You’ll also need the code Telegram will send you via SMS, but that’s only when you log in from a new device.

Today, multifactor authentication is touted as more secure than two-step verification and 2FA.Įditor's note: This article was originally written by Ivy Wigmore. Many other user authentication systems described as two-step verification also qualify as 2FA. Google's 2-Step Verification service, for example, involves a username and password as well as a code sent to the user's device. Many two-step verification products and services are also 2FA. Authentication is an adaptation of verification processes designed to protect access to data and systems. Verification can be part of a real-world process, such as providing a driver's license as proof of identity. Meanwhile, 2FA methods must be two distinct methods - for example, a username and password as well as a facial recognition.įurthermore, verification and authentication are not completely synonymous.
Two-step verification methods include any combination of two knowledge, possession and inherence factors, including repeated factors. Unlike two-step verification, two-factor authentication involves two distinct categories of credentials. Other factors, such as time or location, can also be used. Inherence factors - something you are, including biometrics such as fingerprint or iris scans.Possession factors - something you have, such as a smart card or security token.Knowledge factors - something you know, such as a username and password.The difference between the two is that the sequential methods in two-step verification can belong to the same category of authentication factors, while the methods used for 2FA aren't necessarily sequential and aren't the same factor.Īuthentication factors include the following:
Both involve two steps used for verification.
Many people use the terms two-step verification and two-factor authentication ( 2FA) interchangeably. Two-step verification is a process that involves two authentication steps performed one after the other to verify that someone or something requesting access is who or what they say they are.
