Why You Should go for Two Factor over Single Factor Authentication

Security methods have inclined to two-factor authentication methods(2FA) these days. Moreover, trusting on single factor authentication methods have proved to be dangerous in the history. So even though, it takes extra efforts to deploy an increased layer of security to authorize your users, it’s worth paying the price. Do you want to know, how? Here is some data which will put light on 2FA.

What is Two Factor Authentication?


Well, an added layer of security other than your username and password is called two-factor authentication. It is aimed to save your identity or data from attackers as a username-password combination is not enough to pass the security check.

What do you need for 2FA?

Two-factor authentication methods require some authentication factors.

Knowledge factors: Things which user knows such as shared secret, password or a PIN can be termed as knowledge factors.

Possession factors: Things which users have possession- smartphone, security token or ID card.

Inherence factors: Biometrics- Retina, voice and face recognition; fingerprint. It also involves speech pattern, keystroke dynamics, and behavioral biometrics.

Some more factors to step up authentication: location and time.

Example: Users may require to authenticate from specific time zones and locations.

Why is it better than SFA?

SFA revolves around your password which can be hacked by an attacker if he is provided with adequate time and resources.

Note: Even, using two authentication factors from the same category will not work. Eg: shared secret password combination.

Two-factor authentication steps up your security through providing more challenges in authentication checks. For example, an OTP via SMS can ride along very well with your password.

2FA provides an option to add more methods to authenticate your users. Biometric methods like fingerprint, face and voice recognition can strengthen your authentication architecture.
